Rolling Home (The John Tams version) - but mainly because it's often the last song of a session and I don't want the session to end.
Otherwise anything sung by Chris Gorniak, a singer from Suffolk with the most beautiful deep voice and a lovely line in wistful songs - No More for Me, Bye-Bye Roseanna, Blessed Quietness etc..
He's a regular in the Middle Bar at Sidmouth and the Three Horseshoes' barn at Towersey, and is one of the reasons for me getting so passionate about singing rather than merely listening.
