Or: How we lost the last 20 minutes on Wikipedia. Anyway:

Tom Waits’ pseudolive Nighthawks at the Diner (Asylum, 1975) featured someone named Mike Melvoin on piano. It’s one of our favorite records.

Mike Melvoin’s daughter Wendy is Wendy of Wendy and Lisa and The Revolution.

Mike’s son was the late Jonathan Melvoin, the Smashing Pumpkins‘ touring keyboardist who overdosed in 1996.

Wendy is twins; her sister Susanna is also a working musician, and is married to Austinite and Stevie Ray Vaughan associate Doyle Bramhall II.

Weird.

Update: In answer to the question in the comments, Melvoin has a Bacon number of 2. She was in Toys with Ralph Tabakin; Tabakin was in Sleepers.
