Chicago "Will You Still Love Me?"

Oh, no! What will the band Chicago do without the smooth styling of lead singer Peter Cetera? Thank goodness for bassist Jason Scheff. He stepped up to replace the giant void left by Cetera and the group managed a Top 10 hit with "Will You Still Love Me?" in 1986. This was the first of many hits for the band in the post-Cetera era.

Chicago - "What Kind of Man Would I Be?"

The last time Chicago had a song chart in the Top 20 of the Hot 100 happened in 1990 with the ballad "What Kind of Man Would I Be?".  The tune featured Jason Scheff (gasp!) and not the beloved Peter Cetera on lead vocals.  Despite the parting of ways between Cetera and Chicago, both would continue chugging along over the next three decades.  Chicago most recently has toured with Earth, Wind & Fire while Cetera keeps busy being awesome.
