One of the finest Top 40 stations ever, WLS-890 in Chicago, is running the WLS Big 89 Rewind on Wednesday, July 4th. The one on Memorial Day this year was fabulous, featuring current shows from the likes of Larry Lujack.
You have three choices to listen. With commercials, you can tune to 890 KHz if you live someplace where the WLS signal can be heard. http://www.wlsam.com provides live streaming.
But, without commercials, you can hear an initially 5 hour delayed version (i.e. - beginning at a more sane hour: 9 a.m. Pacific, instead of 6 a.m. Central) streamed (i.e. - not On Demand) at http://www.reelradio.com. The combination of better audio quality and no commercials would alone be worth the $12 U.S. per year subscription price for ReelRadio, let alone the nearly 2000 airchecks on the site.
I did a lot of homework and other activities listening to WLS in the evening from Vancouver in the 1960s. CJVI in Victoria on 900, next to WLS' 890, could be annoying at times. The only station I could honestly say I preferred to WLS was WBZ during the winter of 1964-65, solely because WBZ was then playing new hits first, slightly ahead of WLS.
Here in Edmonton, WLS was the last distant station I found worth listening to, for pure enjoyment. WLS switched to Talk and local CHQT switched to 880, effectively ending my interest in listening to WLS.
To celebrate 89-WLS, RadioWest has changed the number of minutes to count active users to 89 minutes.
