Jocks have been known (to me, at least) to use variations of the "good times, great oldies" tagline, as this is already heard on some of the station's imaging. On the top of the hour ID, the jock usually says "the greatest rock n' roll on the radio, on WKNL, New London." Maybe you were hearing a TOH ID, Scott? Or it could have been Dave Wright, he's used the "best rock n' roll" line, too. Also, Dan O'Brien has the knack of using the phrase, "The most music and the most fun." As well as the aforementioned "best music ever made" line.
