The Beach Boys - Sloop John B (A Cappella)

This is just the vocal tracks from the classic Pet Sounds recording of traditional west Indian song. It really rams home what a group of phenomenal singers the Beach Boys were. There is a harmony at 1.18 that is just amazing. I cannot listen to it without a smile spreading across my face. The melody of this song I think is one that's almost universally pleasing to the human ear. It's been covered so many times, in so many styles that one has to suspect it taps into something that our species finds very hard to resist.
