Definately, the Saturday night of the Scottish music festival, T in the Park, was the most memorable event for me.
REM, the legends of the weekend, while not on their A-game, were CERTAINLY one of the best bands of the weekend. The Flaming Lips were adding the awesome element to the day, after replacing The White Stripes, they put on a show which was worthy of the spot they were taking.
Of course, The Proclaimers playing '500 Miles' live was just great as well, as 40,000 people jumping and singing in unison was achieved. Not even REM could do it.
