addendum

Also... a couple Fiddler on the Roof covers:

Captain Tractor - If I Were a Rich Man
Nice accordion usage on this cover by local Celt-rockers, Captain Tractor.

The Magnetic Fields - If I Were a Rich Man
Another cover courtesy of Amazon.com's free downloads with singer/songwriter Stephin Merritt bringing his distinct musical sensibilities (think: ukulele) to a Fiddler on the Roof cover album. His main band is The Magnetic Fields, though he also releases music as The 6ths, The Gothic Archies, and Future Bible Heroes
