RDB's expedition in the Moke was definitely at the G Club. I was with him on a subsequent visit (in the 80's), and he took great delight in showing me where they had to rebuild the entrance.
He also related the story of another visit to the G Club where he was trying to get to the bar to buy a round, but the crowd was about three deep. At slightly-below-eye-level he spied a very pleasant looking n!pple accompanied by another and only barely restrained with a crocheted top. Curiosity got the better of him, so he "tweaked" it. The reaction from the owner of said n!pple was immediate, as was the arrival of very large (and rather unimpressed) boyfriend.
RDB spent the rest of the night buying them rounds of drinks as penance!
