If anyone is interested in the "Movin' Easy Y97" days of WYNY New York, there's a You Tube soundcheck available. While I was a frequent listener, I realize I hadn't remember the jingles, after listening to this air check.
The first two clips are from "The Rock Pile" when the station was WNBC-FM. That's followed by several WYNY clips from that era, all on this video. We hear Y97 playing Jefferson Starship, Bob Seger, Stevie Wonder, Billy Joel, Steve Miller, etc. all followed by WYNY jingles and a couple of brief DJ artist I.D.s So this was similar to KNX-FM.

Interesting to hear. Thanks for posting. Sounds like 'YNY's cue tones were every bit as tight as the online KNX-FM.
