Good job it was a dub. Think a polystyrene orig of Duke Browner would be starting to hiss by now the number of plays / takes. Bags on the stage is a good point, but the scenes I saw were panning from the back of the hall to the front, and the stage wasn't in shot. Long haired DJ very Curtis / Roberts we thought.
DJs didn't say too much beyond the record and titles and what they did say was pretty muffled at Wigan, and recall Richard occasionally did silly announcements always remember "Lee Moore & The Resourceful Ones and Your love....Keep me....Pissin".
The clapping after individual records is an interesting one, so didn't happen in 74 then? I didn't go that early but did go before I remember clapping each record starting c 77 by the sounds of it. We were also debating if DJs were clapped at the end of sets, not sure that they always were and we thought it depended on the hand over and what the next DJ on said (and whether he got on with the bloke he was following).
Liked the table and chairs laid out, at the back, as close to Wigan table and chairs as you'll get. Not too fussed about the balcony not being the same, as I don't think that'll show too much on the final edit.
