Phil Collins on the Tonight Show on August 11, 1994, during the "Both Sides" tour. The "Nick" referred to near the beginning was apparently Nicolas Cage, who was a guest that same night.
This recording is actually from a rerun on December 6, 1994. My notes said the original air date was August 12, but IMDB says it was August 11 (episode #3.146), so I assume the latter is correct.
