There was a great concertina player Lea Nicholson in the 60's only saw him once at Whitby festival and at the end of his marvellous set he had the nerve to finish with "I'm the Urban Spaceman ".
The audience (most of them) thought it great combining the concertina with a modern song , a bit tongue in the cheek / fun , but it didn't go down too well with the powers that be , and I THAT was that last I heard of him.
Pity really.
Cheers
