 WOGL had moved away from pre-1964 oldies, and Greater Media sought to win away listeners who preferred music of that era.Artists featured on WPEN included Sam Cooke, Elvis Presley, Billy Stewart, Bill Haley, Fats Domino, Ricky Nelson, Billy & The Essentials, Marvelettes, Everly Brothers, Jerry Butler, Beach Boys, The Four Seasons, Jackie Wilson, Bobby Vee, and others.Unfortunately, ratings declined even more.
