What would be your best theoretical gig - opening act and main act?

I've always thought mine would be Traffic opening for Cream as I'm British - but if I was in the U.S. Country Joe and the Fish opening for the Doors would be cool.

Any other preferences?

OASIS opening for PRIMAL SCREAM but only if I could pick the setlist!!!

Desmond Dekker opening for Bob Marley

HORTENSE ELLIS >>> RITA MARLEY & THE SOULETTES

The incredible string band 1968 opening for quintessence 1970.

Jan & Dean opening for The Beach Boys

LOS IBEROS 4 PIC-NIC

Syd's Floyd supported by Skip Bifferty, Tomorrow, 117, Dantalian's Chariot and Tintern Abbey.
