Connolly is also a singer and banjo player. You can watch a documentary he made in Ireland, where he visits the historic Cobblestones pub in Dublin to join in a session going on one night.

He's a bit nervous before he goes, as he hadn't been playing in a session for a while, limiting his practice "picking by myself at home."
