it probably nothing fancy. just the last song played, then on to the new format, like when they changed Y-100 to rap. I heard the aircheck when WJJZ first signed on. Before JJZ, it was Eagle 106. Seemed like it was jockless before the flip. An announcer says "goodbye," then plays Hard to Say Goodbye by Boyz II men, then they played the last song (I Will Remember you by Amy Grant). After that, a DJ came on talking about the new format, then plays the first song (A New Day for You by Basia). It's on airchexx.com I think.
