From the lead story on Yahoo! "Can Video Games Save the Music Industy":
Older bands have benefited from Activision's guitar monster [Guitar Hero], too. Cheap Trick saw digital sales of "Surrender" go from 58,000 in 2006 to 161,000 in 2007, and classic rockers Kansas watched downloads of "Carry On My Wayward Son" more than double from 119,000 to 297,000. Kansas also claims a more visible result of the video game effect: younger crowds. Where previously their shows might have been attended almost exclusively by an audience old enough to worry about interest rates and cholesterol, now they've got front rows "filled with young teenagers."
It's a whole new ballgame, all thanks to video games
Like AC/DC said:
"We're just talking about the future/Forget about the past/It'll always be with us/It's never gonna die, never gonna die."
