That buzzing noise is still there

Wasn't that a cello? Oops, sorry ;-)

slickness of timing at the end of the programme

Yes, on playback it cut off Blowzabella mid-track. Grrrrrrrrr!
But a great choice of music this week (as usual), except perhaps for the choice of version of Matty Groves.

re: the Julie Murphy 'Sylvie' track, this sounded remarkable like Shirley Collins' Nottamun Town.

Yes, yes, do play Crucible and the Old Swans...
