Sorry Helen, must have stepped in to some form of parallel time - not quite sure where I got the 28th from ? It is indeed the 2nd Thursday of the month, and the 13th at 8pm sounds a good start.
I also agree re: location as the region is very large - I never actually made it up to Sutton, but did go to OPC Solihull a couple of times.
One word of warning, there is NO EXIT from the M40 coming North at the A3400 junction. If going North, you will end up on the M42 heading to the Airport and need to come back on yourself at the A3400 (now in effect a right turn off the M40) - awful explanation but you get my drift.
