I'll be heading to Stratford from Liverpool St. -- Haven't worked out which train yet.
Session is 18:00 -- 20:00, correct?
More importantly, where are we going afterwards for beer? If the session finishes at 8, if we get turned around quickly afterwards again (aka "Do one!") we could easily make a Chelmsford pub by close to normal MEMWNS time. Ale House? White Horse? Plough? Railway?
