Aerosmith: Still rocking after 40 years

After 40 tumultuous years together, Aerosmith is one of the last great American rock bands standing. But by the standards of rock music, the band should be long gone.

They are survivors of legendary drug problems and vicious arguments, the kind of which have taken down some of the other groups of their generation.

Yet, with the help of singer Steven Tyler's over-the-top personality and his job as a judge on American Idol, they remain one of the popular concert draws in music.

Correspondent Lara Logan: How good a band is Aerosmith in 2012 compared to the last 40 years?

Steven Tyler: This band is better than it's ever been. It's not because I'm old now and the band's been around forever and it's our last tour. Bulls**t. It's because this band's that good.

The clothes, the rock star posing, the energy...all longtime Aerosmith calling cards, four decades in motion.

Singer Steven Tyler is now 63, lead guitarist Joe Perry, 61, drummer Joey Kramer, 61, guitarist Brad Whitford, 60, and bassist Tom Hamilton, 60.

Tension and drama have always been part of Aerosmith. They formed in 1970 and cut their teeth playing clubs and high schools around Boston.

Within five years, they were selling every ticket they could print, peaking in 1978 when they headlined sold out football stadiums across America.

By that time, they were all drinking heavily and using hard drugs. Tyler and Perry were so hooked on heroin and cocaine they were dubbed the toxic twins.

By 1980, the bands ongoing conflict tore them apart. Four years later, the millions they'd made were gone. One by one they went to rehab, reunited and by the mid 1990s they were as popular as they'd ever been.

Lara Logan: Do you like Steven?

Joe Perry: Yeah. There's sides of him I like and there's sides I don't, you know. But I'll put up with whatever I have to to have this guy in my band 'cause he's got it. He's a world class voice."

Despite their differences, Aerosmith is about to go on tour across America and they're working on a new album. But they're still playing their old classics like the 1977 hit, "Draw the Line"- something these five guys from Boston are still trying to figure out how to do.
