Even though an encore of the WKNR Dream Cruise is in doubt this year, there are still places where you can hear Top-40 radio as it used to be. WABC will again make a brief return to it's glory days as a rocker on Memorial day. The annual Rewound special will be a 12-hour salute to the "Musicradio 77," produced by WABC Production Director and former Musicradio jock Johnny Donovan. JAM Creative Productions prez, Jonathan Wolfert is providing the classic jingles. Airtime is 6am-6pm on May 31.
