Pelham Crescent, Hastings
I don't know if this is allowed but I'm posting it even though I may not be able to go myself due to a family event.
Five hours of live music from The Jukes, The Kytes, Soul Express, Blues Bro Show & Stax of Motown - sounds like a good night with a chance for a bit of bopping.
Tickets £8.50 in advance, available from Hastings Information Centre, Aquilla House or £10 on the door. Proceeds go towards 'Surviving Christmas' and St Michaels Hospice.
I suggest getting there for 7 if you want to grab some seats as these events get pretty busy.
