I got the following from a friend of Bat Goddess's:-

"Hi Jacqui--

As Linn Schulz mentioned, she suggested I email you regarding traditional music in London; sd. you go over frequently. I'll be arriving 13 March and leaving on Monday the 17th. I'll be staying pretty centrally, Hyde Park Radnor near Paddington, so tube access should be easy for me. Haven't looked at buses, but not sure how late I'd be out. I'm not a musician, just enjoy it.
Looking at listings on the Web, I see a tiny place in Soho (?) that has Waterson Carthy on Friday and the Askew Sisters performing somewhere, and a few sessions that seem to be out a bit. Do you know of any regular sessions that are at all central? Any other advice? I've been to London a couple of times now with my husband, but we've been early to bed, and I thought I might try something different."

She won't be there for Sharpes and I don't know what else might be going on in that time frame. Anyone got any useful info?
