Aerosmith frontman Steven Tyler made a surprise appearance on stage with Willie Nelson on Saturday night (02Oct10) as part of a charity show in Wisconsin.
The country legend headlined the annual Farm Aid concert with John Mellencamp and Neil Young to mark the 25th anniversary of the charity the trio set up in 1985.
And the crowd was treated to an extra-special performance when Tyler joined Nelson onstage for a rendition of One Time Too Many.
Tyler was reportedly in Milwaukee, Wisconsin at the weekend (02-03Oct10) to oversee local auditions as part of his new role as a judge on American Idol, according to the Wisconsin Journal Sentinel.
