Pop Master just had a question on SH: "Here's the first Cockney Rebel single, can you name the follow-up?"
And the female contestant got it right: Mr Soft.
But shouldn't Sebastian have been named the first single? Unless the question was "first HIT single" but I didn't hear that.

I heard it too. The question was (I've just i-playered it.....how sad is that?) "You're about to hear the debut hit by Cockney Rebel. Please can you name their next chart entry?"(Judy Teen was played)

I guess, strictly speaking, "Sebastian" was their first hit but not here in the UK. It wouldn't have made any difference to who won the quiz anyway.
