Acoustic jam session in Victoria Park (weather permitting)

This week we're taking our usual Hyde Park jam session to Victoria Park, East London. Meet 1pm near The Pavillion and we'll figure out a place to play. Look for people with guitars. Feel free to bring other instruments too (nothing overpoweringly loud though please). Singers also welcome.
We usually play a selection of pop / rock stuff, with a bit of jamming / improvisation. But whatever people wanna do, really. There may also be convivial eating, drinking and chat.
