The Mike Douglas Show with guests John Byner, Michael Caine, Roy Clark, Mickey Dolenz, Davey Jones, Cindy Williams and Boyce & Hart (1976)

Two notes here. One: John Byner is just the worst. Two: Mickey Dolenz is high as a kite - as becomes most evident at 9:25 of part two.

Hollywood Backstage: Friar's Club Roast of Dean Martin with Jack Carter, Jack Benny, George Burns, Bill Cosby, Joey Bishop and George Jessell (1966)

Rickles with guests Elliot Gould, Michael Caine and James Caan (1975)

All three with moustaches too. From the same special that had this number.
