"Track 10", originally called "Left Handshake", is a single by the Canadian post-industrial band Skinny Puppy from their seventh album Last Rights. The song features samples from the Timothy Leary album Turn On, Tune In, Drop Out which the band failed to receive clearance of from Henry Saperstein, the copyright owner of the recordings in question. Consequently, "Left Handshake" was omitted from Last Rights, but later released as a limited edition CD called "Track 10" in 2000.
