During the recording session of Moby Grape's second album, "Wow", in 1968, Spence attempted to break down a bandmate's hotel room door with a fire axe, while under the influence of LSD. Spence's deterioration in New York and the "fire axe incident" are described by bandmate Jerry Miller as follows: "Skippy changed radically when we were in New York. There were some people there that were into harder drugs and a harder lifestyle, and some very weird shit. And so he kind of flew off with those people. Skippy kind of disappeared for a little while. Next time we saw him, he had cut off his beard, and was wearing a black leather jacket, with his chest hanging out, with some chains and just sweating like a son of a gun. I don't know what the hell he got a hold of, man, but it just whacked him. And the next thing I know, he axed my door down in the Albert Hotel. They said at the reception area that this crazy guy had held an axe to the doorman's head."
