The guys in Aerosmith know there’s definitely such a thing as TMI.

After Wednesday’s night’s appearance on the CMA Awards, Steven Tyler was asked if he’s read Joe Perry‘s autobiography, Rocks: My Life In and Out of Aerosmith. He said, “Hell no. I gotta go on stage with him next year. I want to love the son of a bitch. He hasn’t read mine either. That’s the way it works.”

Tyler’s book, Does the Noise in My Head Bother You? was published in 2011. Joey Kramer is the only other member of Aerosmith to write an autobiography.
