There was a programme that was on either late 80s or early 90s, i think ant and dec were still on byker grove at the time, anyway, it was on CBBC briefly and at the end they sang the song "Hey mickey" or change name of Mickey for the name of the guy that was like the host of the programme. For some reason I think the number five might be in title of the programme somewhere, but might not be, anyone?
