FTSD was rubbish, a complete disappointment compared to It Might Get Loud. Big fat let down IMO, though it had its moments, it wouldn't be particularly revealing to a non-fan either I don't think.
Oh, I will smack anyone who goes down the Gallagher path and claims that 1D > M&S.
M&S aren't that bad, but I do kinda harbour a pathological hatred towards them for being more popular in Australian than the awesomeness that is Elbow simply because they had a hit song which had f*** in the chorus.
