From 1973, please enjoy The Beach Boys and the instrumental track -- with some acapella group vocals at the end -- of their fabulous "Sail On, Sailor."
Just spine-tinglingly beautiful; I should also note that I had never heard this particular version until friend of PowerPop Capt. Al played it on his (400th) intertube radio show yesterday.
I should also add that I'd forgotten that Tandyn Almer had a co-write on this. Almer is perhaps best known for having penned "Along Comes Mary" for The Association, which would be credit enough for a lifetime for most mere mortals, but he also had a hand in "Marcella," the other truly transplendent Beach Boys song of the early 70s.
