Rockers Aerosmith ruined their live shows in the 1970s as they were so wired on drugs.

The Walk This Way hitmakers were renowned for their partying lifestyle, and guitarist Perry and frontman Steven Tyler were even nicknamed the Toxic Twins for their frequent drug-taking.

The rockers are now in their 60s, and Perry is adamant that when he looks back on the band's heyday he is shocked by the negative effect narcotics had on their performances.

He tells Britain's The Sun, "If you're 60 years old, you can't take a tab of acid and expect to come up with genius. It doesn't work like that anymore. All the other s**t gets in the way of the music.

"When I was 20 or 30 it was the other way around. You think you are coming up with great stuff but you are not. I think a lot of other artists our age feel the same way.

"We look back at tapes of the late 1970s, (at the time) we thought it was a great show and we were f**king incredible. But you look back at the tape 20 years later and think, 'We were like statues - standing there and we were barely playing'."

Tyler adds, "The booze can take anyone down. The drug of choice is the music now. There is nothing stronger than Joe and I writing a song and then getting off on that."
