I tend to go with Ken's classification: a session is a performance transmitted on Radio 1 for Peel and his show's audience, whether recorded or live. Thus the live Maida Vale sets by the White Stripes and Super Furry Animals are sessions, but Tom Jones at Glastonbury was not. Tracks played live on air (where Peel and his production team were presumably the only ones present) should also count (e.g. PJ Harvey in 1992 and Loudon Wainwright in 1993, both of which were missing from Ken, but Billy Bragg's in 1995 was included).
