• This group composition about waiting for someone named Gloria is actually "The Painter" with an entirely different set of lyrics; leaving aside parodies, which go back a long, long way, this is something not exactly unknown, for example the UFO classic "Rock Bottom" was recorded initially with an entirely different set of lyrics, and Al Stewart has done this with a number of his songs.
  
  "The Painter" was the 5^th track on the eponymous 1969 album, but although "Hey Bop A Re Bop" was recorded at the BBC on January 14 the same year, it did not see the light as a commercial release until 2000 when it was included on the Remastered second album The Book Of Taliesyn.
  
  Sadly, like not a few other songs it includes the horrible solecism "try and" instead of "try to." >>>
