Well ..... Having followed up all of your very useful advice, and looked at the various websites etc, this is my provisional list:

Thurs 23rd - Sarah McQuaid at Topic FC, Bradford
Fri 24th - can't decide between The Young 'uns at The Grove, Leeds and Kieran Halpin at the Rock Maltby.
Sun 26th - singers night at the Hillsborough Hotel, Sheffield
Mon 27th - Skipton FC
Tues 28th - Ryburn FC
Weds 29th - Singaround at the Woodman, Burneston
Thurs 30th - singers night at the Black Swan, York

Potential a full folking week! This might a bit ambitious, but I will be on holiday.

Advice about who to contact about a possible floor spot at any of these clubs would be very much appreciated.
