I have no wish to get drawn into this! But something that Joe said reminded me of an interview with Moe Ashe (possibly in "Sing Out" magazine). Moe mentioned Ewan, saying that Ewan would fool around in the studio, cracking jokes etc. But as soon as the tape began rolling Ewan became a different man - one totally committed to giving the best performance that he could give and Moe was extremely impressed with how Ewan dedicated himself to giving his best.
