Posthaste: if you've sent a card in to DLT asking to take part in his Breakfast Show, then watch out for the special Radio 1 envelope which may arrive through your door with the invitation to be on the Posthaste Line. Hundreds of cards are sent out with the week's special secret number and may give you the chance, even if you don't own a phone yourself, to chat to DLT and possibly win a super prize by correctly identifying artists or missing lyrics in songs. Each invitation is valid for a week. If you haven't sent in a card yet, write to DLT, Posthaste Line, BBC, London WIA 4WW.
