(Just a few weeks before this show, the Pope had announced a ban on birth control pills (in spite of the persistent rumors that the Vatican had major financial holdings in a Swiss company that manufactured the little devils) To commemorate this, Roy Estrada strides on stage wearing a floor length chain-mail dress with enormous aluminum tits, and an ornate Catholic ceremonial head-dress He is carrying a childs plastic sand bucket filled with SMARTYS (the British equivalent of M&Ms) The inscription on the bucket reads NO MORE UGLY BABIES! While chanting in Latin, he hurls fistfuls of candy into the audience, in lieu of birth control pills
He approaches Ian in his robotically transformed state and begs for an audition as an opera singer with Ians new group, claiming that he has to leave The Mothers -- he's holding the group back because he's a Mexican (He actually used to think this was true, and told me so on several occasions)
FZ:
Then from out of the corner from the stage comes Roy Ralph Estrada perturbed at the present situation within the Mothers
Roy Estrada:
Domino Domino Vo-bisqu-u-u-um
Domino Vo-bisqu-u-u-um
Amen
Domino Vo-bisqum
Hallelujah
Et cum spiritu tuo
Ian, I dont think I qualify for the Mothers

FZ:
They're making up their lines as they go along isn't it thrilling?
Ian:
Why, Roy?
Roy:
Because I don't think I'm qualified I think I'm holding the group back because I'm a Mexican, and also because I don't play bass good
Ian:
I don't care how you can play bass but we have no Mexicans in this group
Roy:
And I wanna join your group
Ian:
No Mexicans!
Roy:
I can sing opera, I cut my hair, I got all my shit together here I can do it
Ian:
I don't care how you look you gotta be able to cut the part
Roy:
I can sing, please, please, give me a chance
Ian:
I don't believe you can sing
Roy:
Please, please hear my plea, please Ian please, I can do it, give me a chance Please, please Oh, oh, oh, please
Ian:
Okay mexican, okay Mexican, sing this note
Roy:
You think everything is gonna be alright
Ian:

Mi, mi, mi, mi, mi
