Yes - absolutely. Dave and Jane, the presenters have put a lot of work into this venture and have welcomed all acoustic singers and players including singer/songwriters, blues, accapella, traditional British folk and the odd American performer.
I would urge all players and singers to go along and give it a try with a floor spot or two and bring your friends. Like all folk clubs, variety is the key to a good night and an enthusiastic audience makes a huge difference to the atmosphere. If you have enough material then email the presenters and ask for a featured guest slot. Guest are not paid but the chance to be heard over the internet and be recorded is an opportunity not to be missed.
