This is ongoing list of amends and additions to the book, referenced via the relevant page. (If you spot an error or have a particularly pertinent nugget of information that you think should be added, please let me know...)

P70
CORRECTION: While it's accurate to say that VdGG performed both 'Darkness (11/11)' and 'Whatever Would Robert Have Said?' for the Beat Club cameras, only an edited version of 'Robert' was broadcast at the time (27 June 1970). Beat Club was in the habit of recording more material than it used, with the full footage of both songs only emerging much later. Clips from the performances of both 'Darkness' and 'Robert' - interspersed with commentary from various talking heads - were first released on the DVD Inside Van Der Graaf Generator in 2005. The full performances were subsequently made available on YouTube. (Thanks to Fred Stöcker for pointing this out)

P85
'Lost' is approximately 45 seconds shorter on original pressings of H To He Who Am The Only One, with the song faded during the "I love you!" section, and cross-faded into the beginning of 'Pioneers Over c'. The longer version appeared on subsequent pressings and reproductions. 

P115
ERROR! The image of Pawn Hearts' front cover is too wide, showing some of the back cover as well...

P171
The Silent Corner And The Empty Stage was also released in the Netherlands.

PH fan Arthur Haswell wonders if "the city is a cage", a key line in 'Modern', is taken from the poem 'The City' by Constantinos Cavafy, as translated and used by Lawrence Durrell in his acclaimed 1957 novel Justine (the first volume of his 'Alexandria Quartet'). Durrell's theme that the external world is a reflection of internal reality, and that the city is a "cage" of one's own making, resonates throughout both the novel and Hammill's own work.

P175 (endnote 2)
CORRECTION: David Jackson was actually first referred to as 'Jaxon' - or rather 'Jaxononsax' - on the back cover of Chameleon In The Shadow Of The Night re 'German Overalls'. (Thanks to Daniel Mercurin for pointing this out)

P175 (endnote 6)
CORRECTION: Roy Harper used the word "erection" in a very fruity context a year before on 'The Lord's Prayer' (Lifemask, February 1973): "A massive erection of pushy defence / Up the whole of the prosecution..." (Thanks to Nick Hopewell for pointing this out)

P176
SPELLING ERROR! That should be "a blank canvas" rather than "canvass"... 

P181
Same error (twice!) in the fourth paragraph.

P270 (endnote 1)
The labels and insert of the Japanese release also referred to the album as Over My Shoulder. 

P282
'The Wave' originally had a completely different lyric and was titled 'This Is Me Dreaming'. It was performed by Hammill during his one-off solo show at the New Theatre, Oxford, 23 March 1976 (see p232).

P314 (endnote 1)
CORRECTION: 'The Mousetrap' actually dates back to early 1976, and was also performed at the New Theatre, Oxford show. 

P333
'Tintagel By The Sea' was based on a song that Hammill had written called 'The Last Cowboy In Space', which perhaps accounts for its ambling, git-on-your-horse rhythm...

P355

​
P408
Hammill has noted that Howlin' Wolf was also an influence on his vocal style.

P433
In his sleevenotes to A Headlong Stretch - The Fie! Albums 1992-1996, Hammill notes that 'Your Tall Ship' was written for his father, who had died during the making of Roaring Forties.  

P434
The versions of 'This Side Of The Looking-Glass' and 'Traintime' that Hammill recorded with the Orchestre National de Lille were released on the 2003 Ange compilation En Vrac.

P461
CORRECTION: I have since revised my opinion of A Grounding In Numbers, which I now regard as a varied but mostly excellent work!

P478
There are two other CD-R releases that I should have listed in the discography:
- 'Work In Progress' (demos for ...All That Might Have Been...), available at Hammill's shows in Japan, September 2013
- 'V/Five New Songs' (demos for From The Trees), available at Hammill's shows in Japan, November 2016

And the next addition to Hammill's discography will be the boxset compilation A Headlong Stretch - The Fie! Albums 1992-1996, which will be released 24 April 2026.

P486
In concert – Radio Munich (Germany) with The K Group:
'Film Noir' and 'The Sphinx In The Face', along with the version of 'Don't Tell Me' recorded for the Dutch Moondogs show (26 October 1982), were broadcast as part of an interview feature sometime in November 1982. It's unknown when or if the entire set was broadcast at a later date.

In concert – VARA radio (Netherlands) with John Ellis & Guy Evans:
CORRECTION: The full title of the festival was the Pandora's Music Box Festival.

P487
In concert - KRO Radio (Netherlands):
Recorded for the show Rocktempel.

CORRECTION: The BBC Radio 1 Saturday Live show, 25 August 1984, was not a live session - Hammill was interviewed, but the tracks listed were played from The Love Songs.
