Ian:
My name is ian underwood
And i am straight member of the group
( wowie zowie)
One month ago i heard the mothers of invention at the theater
I heard them on two ocassions
And at the second ocassion
I went up to jim black
And i said i like your music,
I'd like to come down to play with you.
Two days later i came up to the recording session
And frank zappa was sitting at the control room
I walk up and said
How'd you do, my name is ian underwood and i like you music
And i like to play with your group.
Frank zappa says
What can you do is fantastic
I say i can play alto saxphone and piano
And he said
All right, whip it out....
