I have been a fan of Peter Cetera for many years. When I found out that he was a singer for Chicago, I was hooked and have been listening to Chicago ever since. I thoroughly enjoy this CD. It has some of my favorite Chicago songs. BUT...why does Chicago need so many greatest hits compilations. I purchased The Very Best of Chicago: Only the Beginning when it came out it is absolutely the best GREATEST HITS career retrospective from Chicago. If you are new to Chicago (the band) this album is an excellent source of hit music it even includes some music from XXX album. But if you want more music get the other album.
