Ahoy! There be pirates. Tom Waits and Keith Richards sing Shenandoah
Here's an inspired duet by Tom Waits and Keith Richards on the song "Shenandoah" from the album Son Of Rogues Gallery: Pirate Ballads, Sea Songs & Chanteys.
Yup, definitely sounds like a bunch of pirates wailing over a pile of pints. Just beautiful.
And if you liked that, here's Shane MacGowan with Johnny Depp and Gore Verbinski with "Leaving of Liverpool" from the same album.
