I'm afraid the WABC situation is unique. While I have so many fond memories of WABC, WFIL and WIBG, I see a difference in their histories once the slide started. When Famous 56 died, it DIED. It even became WEAZ-AM for a term, before Salem bought the WFIL call. WIBG became WZZD and died a horrible death before taking the current call letters. The call letter changes are significant when doing a rewound show.Besides a brief fling with disco, WABC seg'd successfully into AC before making the big switch to News Talk. And it was not a sudden move. Announced ahead of time, they let Big Dan and Ron Lundy do a final tribute show and launched the new format with an hour long tribute to Music Radio 77 as their first talk show. WNEW-FM did a long form tribute to the former Top 40 powerhouse, since many WABC listeners had long before switched to 'NEW-FM, which in 1965 got WABC dj Scott Muni.WABC did everything possible to lure their Top 40 listeners to their new format. And as the format developed, it worked. From being the most listened to Top 40 station in the USA, they have become the most listened to News Talk station in the country. While WFIL and 990 drifted into a nitch positions, WABC remains a powerhouse. Many of the Top 40 listeners are still loyal listeners. People all over the country have WABC memories and during the winter many of them, including me, were again listening Saturday nights to Mark Simone.Doing a rewound day for a station/stations that have not had broad appeal for over 20 years is far more difficult, if not impossible, to pull off than on a station that continues to be a major power in their market. I loved the reunion weekends on WOGL, but a rewound presentation would be far more difficult to produce. And obtaining an audience on the actual stations, which now have low numbers, might make it unworth the significant work involved. Johnny Donovan works all year to produce the Memorial Day 12 hours of shows. Who would be able to pull that off in Philly, even if enough tapes still exist.Frankly, I suggest that we a form of rewound available on the great Hy Lit web stream and we owe Hy and his staff a vote of thanks for putting that on our pc's!
