GH1 had Hendrix, and Harmonix had the respect to omit vocals to honor Hendrix. I doubt Neversoft has any fucking respect since they're a POS studio and Joel Jewfag is exactly what his last name is.
Also all this hubub over lips is undeserving. Anyone remember Xbox Music Maker? Microsofts karaoke game that was a rip off of Karaoke Revolution's success? Yeah, it sucked big time and had the same features as Lips.
