I met Clancy Imislund (not to be didactic, but note spelling) last year. He's run the Midnight Mission in downtown LA since the latter Boss Radio days. He's 86, appears to be healthy as a horse, and has an incredible life story.
What I never understood was why Drake let the "Boss" sloganeering go on as long as it did. '65 thru '67 maybe..already outdated sounding...but IIRC, "boss" continued until about 1970, way past it's sell by date. "Groovy" had already been used and discarded by that time. Hella lame, dude.
I suspect KYA meant "Boss of the Bay," more like we're the best, we're number one- which I guess they were until KFRC came along. In the early 70s, KYA was 'the Rock of the Bay"....rhymed with "Dock of the Bay."
Llew: Thanks for the correction on the spelling. Clancy has lived an amazing life and deserves to at least have his name spelled right.
As for "Boss", it was probably viewed as a tricky thing to walk away from, since they had so much tied into it..."Boss Angeles", "The Boss 30", the Bossline, Boss Jocks and, on KHJ-TV, "Boss City". The TV show was the first to change, becoming The Real Don Steele Show in 1969, jock references to "Boss Angeles" stopped that year, too...and jocks stopped referring to each other as "Boss Jocks" around that time.
But the "Boss 30" and "Bossline" survived until May first of 1971, when they became simply the "Thirty" and solicitations for requests were down to "Got a song you want to hear? Call me from L.A. and the Valley at 520-1971."
