Joe writes: Amarillo by Tony Christie was a modest hit in its day, but a huge UK no. 1 in recent years. Dominick The Italian Christmas Donkey wasn't a hit in its day, but it will be the Christmas no. 2 in the UK this year. Sadly the lesson in both cases is that no-one makes music with these qualities anymore, so these tracks stand out from everything else around them.
Incidentally, Lou Monte did have two novelty hits in America but neither of them were as good as this.
