​Watch Jimmy Fallon and Kevin Bacon Perform an “Early Version” of Tom Petty’s “Free Fallin'”

Jimmy Fallon is no stranger to impersonating classic rock greats, having stepped into the shoes (and clothes and wigs) the likes Neil Young, Bob Dylan and Bruce Springsteen. Last night (August 29), he added to his repertoire, teaming up with Kevin Bacon to perform as ELO's Jeff Lynne and Tom Petty, respectively.
 
The duo delivered an "early version" their co-written Petty hit "Free Fallin'" — one that really drills home the protagonist's love horses.
