Such Great Heights

I was wondering whether the song "Such Greath Heights" was originally by "The Postal Service" or "Iron & Wine."  I've always heard that it was by "The Postal Service," but I was listening to the All Songs Considered podcast from May 17, and the lead singer of The Postal Service (Ben Gibbard) introduced the song with "This song is by Sam Beam" (id est, the singer of Iron & Wine).  So, which is it?  ¯\(°_o)/¯

Also, lol indie folk / pop sucks

I hate all the bands you like.

it would help if you could spell 'great' though.
postal service ftw

I believe it's by The Postal Service. Iron & Wine covered it for the Garden State Soundtrack. Both versions are good though, just enjoy 'em :]

Such Great Heights would be awesome if it didn't have Ben Gibbard singing on it.
