Thanks for the info...
I wonder how accurate the online listing is - I understood the band played at Parham, not Podington as stated, on 23rd August 1944 (for the 200th mission party of the 390th Bomb Group).
My main aim is to confirm whether or not Glenn Miller played at Sudbury (Suffolk) airfield - although I suspect not. There seems to be a good deal of confusion over the venues; for example, some publications and online sources say the band appeared at Earls Colne (323BG), which has never been confirmed.
