Well, the absolute best would be Bird and Zappa
improvising over a
song about drug abuse....
I have a vinyl record of anti-drug messages compiled for radio station
use in the 70's. One of them is 'This is Frank Zappa, asking you to
un-load yourself!' Mind you, another has Alice Cooper saying 'if I
ever find out any of you have been taking drugs, I will personally
come round to your house and kill all your puppies'. Sounds like that
could have backfired for some kids...
Cheers
