(CBS News) They are still rocking and still fighting 40 years later - the legendary American rock band Aerosmith. One reason Aerosmith is selling out stadiums is because its front man, Steven Tyler, has become an American Idol sensation. The other is because they still make great music, for which Tyler takes much credit. He tells Lara Logan: "I think my perfectionism and my busting everyone's chops is what got this band to where it is today." It's amazing the band is anywhere today. Decades of drug addiction, vicious arguments, and serious illness have destroyed many other bands of their generation, but Aerosmith rocks on.
