When I saw Paul Simon in 91 or 92 (Rhythm of the Saints tour), he played You Can Call Me Al and the whole place went nuts, so much so that he said "You wanna hear it again?" and then he played it again! Which just made the people go more crazy. I remember thinking "Wow, that was pretty special" but then I read in Rolling Stone that he did that at every show and I was kind of disappointed in a sad way.
