Don Rickles passed away on Thursday (April 6) at the age of 90, leaving behind a legacy as one of America's all time great comedians.
Rickles was a two-time Grammy nominee in the best comedy album category for his albums Hello Dummy! in 1969 and Don Rickles Speaks! in 1970, but his career's musical highlights exceed the award show.
From soundtracks to TV interviews, live performances and more, here are six of Rickles' best music moments.

Rickles guest starred in a 1997 episode of Muppets Tonight, which also featured Coolio, and for reasons too confusing to explain here wound up dressed as Kermit the Frog performing the character's classic hit "It's Not Easy Being Green" (skip to the four minute mark). It doesn't go according to plan but is pretty fun regardless.
