Assembling a backup band for an elderly man with terminal cancer

Hi Everyone, I am a documentary filmmaker in Rockaway Beach, and one of my subjects is an elderly man who loves to sing and is suffering from terminal cancer. If we could get a band together he would love to put on a show and sing for a crowd at a local bar. Looking for people who can play the guitar, bass, keys and drums. Even better if we can find an existing band! He put together this list of songs: Johnny Mathis- the twelfth of never Frankie Avalon- Venus Bill Withers- Lean on me Barry Manilow- there’s a kind of hush Please let's make it happen!
