The strangest segue I heard on True Oldies was Shelly Fabares "Johnny Angel" with a quick liner and then Rare Earth's "Get Ready".
Aw, that seque was nothing... This morning on KRVT I went from CB's "Johnny B. Good" to Joe Tex's "I Gotcha". Of course of you're doing it live, you can buffer the audio whiplash to some extent.
I look forward to getting far enough west to listen to the new KZLS. (BTW, is that the same station that Lacy, et al put on the air years ago up around Enid?)
