Billboard called The Buckinghams "the most listened-to band in America" in 1967. Today on WTMJ Conversations, guitarist Carl Giammarese tells Libby Collins everything about the Chicago pop outfit, including having the number one song in the country while being a senior in high school, playing on the Ed Sullivan Show, singing some of the most memorable jingles of all time, and so much more. It's all ahead on this chart-topping edition of WTMJ Conversations!
