Oh boy, Michael! Oh boy, David! Oh boy, everybody else! I found the KHJ-FM playlist. It's from mid-December 1971 and has 30 songs, including Sweathog, Melanie, Badfinger, Dennis Coffey, N.F. Portyer (!), Donnie Elbert, John and Paul and George---but no Ringo---and the English Congregation. I posted it on page 16 of the KRTH thread at

Right. That was (as it says right on the playlist) from the "Solid Gold Rock And Roll" format. 80% gold, 20% currents. And that's the list of currents that made up the 20%.
Comparing it to the KHJ "Thirty" of that week, KHJ was playing album cuts KHJ didn't list (Cat Stevens' "Changes IV", Carole King's "Brighter", Paul & Linda McCartney's "Some People Never Know", Aretha Franklin's "Oh Me Oh My", George Harrison & Leon Russell's "Beware of Darkness" and George Harrison's "Awaiting On You All"), and five singles KHJ wasn't playing (Sweathog's "Hallelujah" and Sonny and Cher's "All I Ever Need Is You", both of which had already dropped off the Thirty, Three Dog Night's "Never Been To Spain", which KHJ would add two weeks later, Carole King's "Sweet Seasons", which KHJ wouldn't add until January, and J. Geils Band's "Looking For A Love", which KHJ never played). KHJ didn't list John & Yoko's "Happy Christmas", but they did play it.
KHJ was also playing songs KHJ-FM didn't (Bread's "Baby I'm A-Want You", Les Crane's "Desiderata", The Temptations "Superstar (Remember How You Got Where You Are)", Rare Earth's "Hey Big Brother", Yes' "Your Move", Isaac Hayes' "Theme From Shaft", Lou Rawls' "A Natural Man", B.B. King's "Ain't Nobody Home", The New Seekers' "I'd Like To Teach The World To Sing", Chase's "So Many People", Michael Jackson's "Got To Be There", Joe Simon's "Drowning In The Sea Of Love", Robert John's "The Lion Sleeps Tonight", Apollo 100's "Joy" and Bullet's "White Lies-Blue Eyes").
On the 18 songs they shared in common, KHJ-FM was several weeks ahead of KHJ on some (4 weeks ahead on Three Dog Night's "Old Fashioned Love Song"), but never more than three weeks behind ("American Pie").
Still, that's 12 songs that they don't have in common (both stations have lists of 30, 33 if you count KHJ's Hitbounds). And if I remember the Drake-Chenault "Solid Gold" format clock, it was designed for 14 minutes of commercials an hour. That left 46 for music. Subtract jingles and IDs, you're at 45, average song length 3 minutes and you're playing 15 songs per hour. At 80% gold, they were only playing three of those currents per hour. So, not a Top 40, but an interesting hybrid of oldies, hit singles and a bit of album rock.
