I do the website for The Topic in Bradford, the soi-disant longest-running weekly pub-based English-style folk club in the world (est. 1956, and this Xmas Day will be the first dark club night in 5 years) and there were quite a lot of women performing in 2008, more than usual (anyone wanting to analyse this can look back over all the gigs for all the years pretty much to 1970 on the site).
Not all of these were headliners. Some - Tuppenny Ceilidh Band, Pillowfish, Danyluk and Card - are male-female duos. Some acts - like YLEM, Celtish, Bandersnatch & Dark Horse - are bands with more males than females. But there were several solo women and also "duos" - such as those with Debra Cowan, Emily Smith and Kirsty McGee - where I think it fair to say the woman is the driving force and/or lead attraction.
Plus there were three all-woman acts - Ember is two, Bryony three and Soundsphere four women (and all were headlining).
Here's the whole list for 2008:
David Moss and Masha Kaestner
Katriona & Jamie Roberts
Emily Smith with Jamie McClennan
Ceri Rhys Matthews and Christine Cooper
Debra Cowan and Pete Smith
Peter & Barbara Snape
Danyluk and Card
Chris and Siobhan Nelson
The Tuppenny Ceilidh Band
Pamela Ward and Paul Cherrington
Paul Wrigley & Sue Burgess
Kirsty McGee and Mat Martin
Fiona Katie Roberts
My brother John booked the acts for 2008. Next year booking is being done by Rahel Guzelian, and so far she has booked:
