Great guitar requires a great song. Yesterday, all my troubles seemed so far away Now it seems as though they're here to stay Oh, I believe in yesterday Go on Suddenly, I'm not half the man I used to be There's a shadow hanging over me Oh, yesterday came suddenly Why she had to go, I don't know, she wouldn't say I said something wrong, now I long for yesterday What the hell was that? Yesterday. When did you write that? I didn't write it. Paul McCartney wrote it. The Beatles. Who? The Beatles. The what? John, Paul, George and Ringo. The Beatles.
