Should have said.. 20th September.
Will actually be on two nights. There's a half hour show on the Tuesday (20th) and an extended version on the Friday (23rd)...
Later is a TV show broadcast in the UK by the BBC. It has an excellent reputation for showcasing all kinds of musicians playing live. Let's hope this helps to remind some oldies about him, and introduce him to some not-so-oldies...
