If you're around the Merseyside area, you might want to stick your head into the Modrophonic event in Liverpool.
A charity event in aid of Help for Heroes, it takes place on Saturday 24th July 2010 from midday to 2am (14 hours in total) at the First National wine bar, James Street, Liverpool.
£5 entry gets you in, with a rideout to the venue to start the event off from Speke to Derby Square. As well as the bands (on flyer above), there are also raffles and various other bits and pieces. No contact details, so if you want to know more, check with the venue.
