Because it's Friday: Five musicians, one guitar
Check out this cover of Goyte's "Somebody That I Used to Know", played on a single guitar by all five members of Walk Off The Earth:
Incidentally, the Gotye original version is the first song by an Australian artist to reach #1 on the US charts since Savage Garden in 2000. There's so much good Australian music it's a shame more of it doesn't make it to the charts over here in the US. But this is still a great song, so enjoy it as a kick-off to your weekend!
