Here's one for radio geeks (and music lovers). Very few people appreciate the precision that goes into singing radio jingles. You have six singers, different harmonies, and they have to be absolutely in perfect sync. It's a very specialized field. (Clayton Kershaw's father used to sing radio jingles for many stations around the country.)
Radio jingles are the signature of a station -- the Golden Arches. Mention KRTH to anyone in Los Angeles and they'll automatically sing "K-rth 101." I'm sure there are stations in your market that you identify by their signature jingle.
Jhani Kaye, who was the program director of KRTH in Los Angeles, videotaped a jingle recording session from 2007. He just recently uncovered the tape and posted it on YouTube.
Leading the session is Johnny Mann. Sad to say he passed away a few years ago. But he was quite famous for creating radio jingles in the '60s (e.g. the famous KHJ "Boss Radio" package) Additionally, he recorded albums (the Johnny Mann Singers), and hosted a syndicated flag waving/patriotic sickeningly wholesome syndicated series called STAND UP AND CHEER.
Don't know the names of all of the singers, but I do know the lead singer (the blonde on the left in the green top) is Grammy winner Darlene Koldenhoven. (There are a couple of shots when they show the people in the control room and you might spot me for a second or two.)
Darlene is a friend and there have been times she's been in my car, I'll have KRTH on the radio, a jingle will come on and she'll sing along with it. Everyone sings in the car, but rarely do you hear the actual person singing live with herself. If only I could get Adele in my car. (Maybe if I said I was James Corden.)
Now a note about watching this: You (hopefully) will find it fascinating to watch the precision of these fine musicians as they weave through very complicated vocal charts very quickly. (Brian Wilson, if you're reading this, you're welcome.) But the repetition might start driving you bonkers. I suspect many of you will watch for a couple of minutes, get the gist, and move on to your Facebook page or porn. But some radio nerds will stay with the whole twelve minute video and then watch it again seventeen times.
In any event, you'll be singing "K-rth 101" in your sleep.
