AXS-TV just released a preview clip of Chicago co-founders Robert Lamm and Lee Loughnane sitting down with Dan Rather on The Big Interview.
Reaching back into the band's history, Lamm recalls when they played the Whisky a Go-Go in Hollywood. One night after a gig, the melody and then the words for "25 or 6 to 4" came to him.
The Big Interview airs Wednesday night on AXS-TV.
