There are many scenes that are WTF?!? Moments in this mess- Elderly celebrities embarrassing themselves, Jackie Gleason tripping on acid, Carol Channing doing a striptease in front of Frankie Avalon... But the scene that tops them all for bizarreness is actually the credits. Otto Preminger himself, sounding like Colonel Klink, asks the audience to stay in their seats while Harry Nilsson sings the end credits. It's as bizarre as it sounds and the "song" even made it onto the soundtrack.
While the rest of the soundtrack (aside from Ms. Channing's croaking) has gained some fans over the years, the bizarre song from the most bizarre film of the 1960's still holds up as an example of what happens when Hollywood tries too hard to be hip.
