After the seriousness and maturity of Chicago’s “(I’ve Been) Searchin’ So Long,” it’s time to party!

If Chicago had to go mainstream, this track was the way to do it. No apologies were necessary.

“Happy Man’ is the least-bombastic vocal Peter Cetera ever recorded with Chicago, and I’m including “If You Leave Me Now.”

Part of the appeal of Chicago’s “Lifesaver” is that it’s fun – a stark contrast to the pretentious seriousness of 1973’s ‘Chicago VI.’

Chicago’s “Hanky Panky” shows a versatility at Peter Cetera’s instrument for which he never truly receives due credit.

You won’t find this on anyone’s list of Top 10 favorite Chicago songs, but “Italian from New York” proves just how versatile they were in the ’70s.

Let’s start by saying jazz-fusion normally isn’t my cup of tea, so Chicago’s lengthy instrumental “Devil’s Sweet” came as a surprise.

Chicago always denied being a jazz-fusion band. The opening songs on 1974’s underrated ‘Chicago VII’ say something different.

“Tired of Being Alone” has the greatest lead vocal on any officially released Chicago song – and that’s an insult to no one.

Chicago’s Terry Kath delivers a raw, emotional performance not unlike John Lennon’s brilliant but bleak ‘Plastic Ono Band’ album.
