I was listening to my local radio station Smooth Radio last week during their listeners favourite song request show. A woman who I would guess was in her 60's said could you play Everyone's gone to the moon by Jonathan King, to which the presenter at the time finally replied after much stuttering "errm I dont think we have that one here at the moment".
He ended up playing 'Blue Moon' by The Marcels. I found it quite amusing as I've never heard a radio presenter lost for words in such a way.
