Looking back in my last.fm account and apparently I saw Muse in 2009 in BIRMINGHAM when I NO LONGER LIVED THERE???

I do not remember seeing them AT ALL, although there are old reminder emails I’ve sent myself from my work address around then saying to bring Muse CDs to lend my work colleague and what time she’s coming over on the day of the concert (3.30pm). I mean… she must have bought the tickets since I don’t have those emails but???
