As the CD's subtitle says, these tracks are from various BBC radio sessions recorded in 1977, 1978, 1979, 1982, 1984, and finally in 1989. The earlier dates are John Peel sessions, with later tracks from shows by David Jensen, Bruno Brookes, and Andy Kershaw. The tracks don't differ much in style from the original studio albumss, but the sound quality is very good and the performances most satisfactory. Maybe not an essential purchase, but one that I think most diehard XTC fans will be very happy to hear. Some great songs that I never get tired of listening to.
