Tonight at 23:35 on BBC2 Terry Wogan hosts a chat show celebrating the 20th birthday of Radio 1. With guests John Peel, Tony Blackburn, Bruno Brookes, Janice Long, Mike Smith, Dave Cash, David Symonds, Ed Stewart, Pete Murray, Carl Wayne and Johnny Hates Jazz. Lots of chaff, too little wheat, but I'm sure there will be a little gem in there somewhere.
