The Easybeats were the first Australian band to have a hit outside of Australia.
This was not that hit, but it was a minor international hit for another band. This version, featuring a guest vocal by Steve Marriott of the group Small Faces, hit #22 in Australia in 1968. The song itself is a lot of fun and oft-covered for that very reason.
It's also one of my favorite songs from the 1960's, and not just because of INXS and Jimmy Barnes.
