In early 1970 Mike McCormick
returned to WLS from KQV in Pittsburgh and became program director of WLS
and the changes began. The Big 89 became The Rock of Chicago. The jock
lineup included Larry Lujack, Gary Gears, Fred Winston, J.J. Jeffrey, John
Records Landecker, Bill Bailey and Joel Sebastian. Charley Van Dyke and
Chuck Knapp would also join WLS during this period.

A new jingle package was purchased from PAMS
of Dallas, "Solid Rock". The Studio C singers were used instead of the
original vocal group. Ken R described it this way, "This package used a
younger rock-oriented vocal group in the style of "Jesus Christ Superstar"
which was popular at the time. The style was copied by the other jingle
companies, but PAMS was very successful with this series."
A second package was put on the air in
April, 1973 produced by Jodie Lyons Productions, called "The Rock of Chicago."
