ace, i just noticed one of them was drinking Grolsch with the fancy lids and two bottles were left aside from recycling - nabbed the little red rubber bits for extra guitar strap locks, natch.
weird coincidence though as BOTH guitarists at the gig earlier had their strap come off mid-song (nae strap locks, tsk) and i thought “that reminds me, must get a couple of bottles of Grolsch soon, i could do with a couple more of those things”
