David Bowie contributed to Ava Cherry
covering Frank Zappa's 'How Could Be Such A Fool'.
Around 1966/67 Bowie had already recorded and/or other Zappa songs ('It Can't Happen Here', 'Who Are The Brain Police') with his bands at the time, the Buzz and the Riot Squad.
During his 2003/10/30 concert in Vienna, Bowie referred to Zappa's 'It Can't Happen Here'. Asking the audience if anyone knew this song.
in the late seventies, adrian belew played guitar in bowie's band:
On 2003/10/30 "Camillo" wrote: I just returned from today's David Bowie concert here in good old Vienna. During the band intro he noticed that his female bassist did not wear a long shirt - just a jacket above smaller shirt - so You could see quite some skin. And DB went "Could imagine" - just as Uncle Frank did on FO!. Then he said, that this was from a song called It can't happen here from Frank Zappa, and wanted to know how many people here tonight knew this song. He actually asked two times.
And "Shiborugu" added: I bet nobody here knew David Bowie played in a band called "the Riot Squad" in the mid-late 60's that covered "It Can't Happen Here", "Who Are The Brain Police" among others...
