Leadfingers - the song you're thinking of is by Samuel Laycock but is about the same subject. I knew Sid had done the recording for this a few months ago but I don't know if he said what "Surat" was during the interview but the programme didn't explain what the significance of Surat was.

It was a great piece featuring history and song and was well presented.

If you liked the piece then write to the BBC saying you want more of it. info@bbc.co.uk should get comments to the powers that be.

Cheers
Mark
