...hopefully not too difficult. Andy Nogger is the 3rd album by Kraan. Said by some to be their best effort, but I think the live albums (of which there are several) show better what the band can do. The title track doesn't give much clue about whether he was a real person:

"Andy Nogger is no He-Man
He is a dressman and a Yes-man
He's so young and he's so dashy
His strong teeth are white and flashin'

Andy Nogger needs a gaylight
Always new cars 'n' she doesn't drive
All the women like this boy
They would like to be his soil..."

Indeed....! Sounds rather like a Kraut David Watts.

Apparently "Kraan" means faucet in Dutch, being being German the band didn't know that, they just liked the name!
