The Lancaster you mention is part of the Battle Of Britain Memorial Flight which is based at RAF Coningsby in Lincolnshire. This year it is in the colours of 61 Squadron 'Mickey The Moocher'.
Please see this link -
http://www.raf.mod.uk/bbmf/bomber.html 61 Sqn had been at many bases throughout middle England. They were at RAF North Luffenham (Rutland) with Manchesters before moving just up the road to RAF Woolfox Lodge where they first received the Lancaster. From there they moved to RAF Syerston near Nottingham which also meant having some planes at St Eval. They then moved briefly to RAF Skellingthorpe (Lincs?) before moving to RAF Coningsby. Back to Skellingthorpe they went. They also were are Sturgate and RAF Waddington.
As mentioned in the BBMF write up, Mickey The Moocher went onward to 1653 Heavy Conversion Flight which was actually based at RAF North Luffenham (very fond of that place as I used to work there!).
Anyway, I was at Coningsby not so long ago and the Lancaster started her engines and took off whilst I was there. If I can I will try and get in touch with someone from the flight and get some sound recordings, though it maybe some time.
