I think on both the tracks ( despite Urban Spaceman being from TOTP2 , I think original must have been the same CMP session ) , the record track has been used , rather than a morning session take as there is no variation to the musical tracks at all from the disc. Thats not to say the Bonzo's couldn't do a note perfect reproduction , just I dont see it in their nature given a live or near live opportunity to do so. I think there is a video clip of the guitar solo in Canyons that uses a slight variation in the notes played, possibly done at a much later time.
Sweet essence of Giraffe. It was truly a moment of human greatness when Viv reappeared wearing the large papier-mâché head from stage right. He was the student who submitted Godzilla -vs- Oscar Wilde for his Diploma at St Martins.
The Colour Me Pop performance was a typical BBC setup for the time. The band mimed to the pre-recorded backing track whilst Vivian Stanshall sang live hence it's a different vocal, his burps are different... notice too when he's wearing the large false head - his vocals are more muffled!
As can be seen on the last two scans the record with the alternate take on the B side has noticeable differences in typeface and, most useful for identifying purposes, the publisher credit below the side number now reads "Bron Music Ltd." instead of "Bron Mus. Ltd."
There are 2 versions of this single with different takes of the B side.
The B1 take is as the LP and the B//2 take is as they performed it on "Do Not Adjust Your Set" with a spoken intro. The first take is available with a push-out centre and the large centre hole but I have never seen a copy of the second take with a push-out centre.
