Sadly they didn't have a go, leaving that to some Xbox staffers instead. In fact, Macca and Ringo seemed a tad perplexed by the whole thing. Yoko was also on hand to say hi, but it was the surviving Beatles who got the biggest cheer.
The game is due to land in September, with downloadable songs to follow. Abbey Road will be available in its entirety, with All You Need Is Love as an Xbox exclusive.
I'll be getting my hands on Beatles Rock Band when the show opens tomorrow. Hopefully Paul and Ringo will be on hand to help out. Here's hoping eh?
