Happy birthday to former Chicago front man Peter Cetera.  The pop star turns 69 today.  Chicago is most well known for their extensive use of brass and a rock/jazz fusion sound in the early 70s. 

As the band evolved in the mid 70s, their sound turned more to a focus on Peter Cetera's strong vocals.  Peter turned that success into a solo career beginning in 1986.  Though he doesn't perform with Chicago these days, Peter continues to perform.

We're going to rewind to 1985 for Chicago's "You're The Inspiration" from the album Chicago 17, the group's last with Peter Cetera as its lead singer.
