Since it's been 30 years since Jhani forever changed the image of AC, I've dug out the KFMB aircheck I was talking about and one from KMPC from two months later. Here's how they played out. The KFMB aircheck is only 30 minutes, so we'll compare half-hours.

4:27 PM: Henry Mancini: Theme From Oklahoma Crude (current...Gary talks up intro)
1973 was the year KMPC was transitioning from MOR to AC...and they were pretty much all the way there by this June aircheck. The Henry Mancini single was about the only nod to the old music. Again, KFMB had failed as a Top 40 in 1972, and was coming at AC from the opposite direction, keeping the audio processing, pacing and production values, going deeper with the gold (and playing more of it ) and simply not playing a few songs from the current top 40.
Looking at KHJ's Thirty for that week, there are only 8 songs I'm sure KFMB wasn't playing: War's Cisco Kid, The Sweet's Little Willy, The Temptations' Masterpiece, Edgar Winter Group's Frankenstein, David Bowie's Space Oddity, Steely Dan's Reeling In The Years, Lou Reed's Walk On The Wild Side and First Choice's Armed and Extremely Dangerous.
I'm betting KMPC passed on those and Skylark's Wildflower, Dobie Gray's Drift Away, Stealer's Wheel's Stuck In The Middle With You, The New Seekers' Pinball Wizard/See Me, Feel Me, Loudon Wainwright III's Dead Skunk and The O'Jays' Love Train.
