The studio is Music Bank London,
www.musicbank,org.
Rehearsals took place according to Guy Fletcher's diary in Sept.: In the 5th Oct. 2011 entry he states that
"only 2 weeks ago, the band assembled for rehearsals in the usual location in East London." , so second half of September. Richard Bennett posted on Sept. 24th,
"I don't want to sound boastful, but honestly we could do a show tonight just after this week of playing together again."So rehearsals obviously took place from 19.09 until 02.10., at least that's my guess.
I think we won't get any closer to the exact date.
All the Deluxe Edition says is: Bonus disc live from rehearsals. Recorded by Dave Dixon. That's all. Maybe you should ask Guy! He will be happy to answer these kinds of questions!!!
