In my opinion, AM 1260 as KSUR ("Oldies 1260"), WITHOUT rebranding it as "The Shuffle." That was the kiss of death for a once-great oldies station which likely because of declining ratings and whatnot due to the rebranding (which lasted all of five days[!]), went back to the tried-and-true adult standards format. Oh, that Saul Levine, always fixing what ain't broke!
In fact, considering how many formats and call signs have called the 1260 frequency here in L.A. home over the years, does anyone else have an opinion as to what station on 1260 deserves a second chance?
BTW, I wonder how much longer for this world their current call sign and format (KGIL, "Retro 1260," a mix of the two aforementioned formats) is?
