I didn't go to the Kirsty MacColl memorial concert on Monday. Much as I love Kirsty's songs, I had misgivings about hearing them possibly being butchered by a cast of well-meaning friends and admirers. The reviews of the show have been positive, and - thanks to the BBC's new digital radio channel 6Music, I can listen to highlights from the show, and from Janice Long's documentary about Kirsty, online.
