The album “
Chicago V”, the group’s fourth studio album, reached number one on the US album chart, the
Billboard 200 (Billboard Top LPs and Tape), in its fourth week, beginning a nine-week run at the top. It knocked
Elton John’s “Honky Château” from number one, while
Alice Cooper’s “School’s Out” fell to number three, followed by
The Carpenters’ “A Song for You” and “
Simon and Garfunkel’s Greatest Hits”. “Chicago V” marked the beginning of an important period for the group and became the first of five consecutive albums, including “Greatest Hits”, to reach number one. The album’s success was significantly helped by the million-selling single “Saturday in the Park”, which reached number 3 on the US
Billboard Hot 100.
