I saw Motley open for Aerosmith, and it was painful, just trash. It's a shame, 'cause I was ready to be impressed. I think Vince sang maybe 50% of the lyrics that night. He kept stopping halfway through lines and foisted the mic at the audience "YOU sing it!". No Vince, you're the rassin frassin lead singer. I paid to hear you, not them. Maybe you should have stayed home.I think Motley Crue was the only show I ever walked out on too.
They also had political junk playing on their rear projector and took an eternity between songs, during which we were "treated" to a ground hum problem which featured what sounded like phase, flange, delay, reverb, chorus, and probably 12 other effects. It was never corrected. They stank on ice.
Aerosmith then came out and effortlessly pummeled them into the ground with, you know, a performance.
