That I can't answer, because I've only heard the piece on the episode itself, and I've never been a connoisseur of clasical music, but when it comes to the "noise" Beau Williamson listened to, if you take a close look (in case you hadn't noticed this before), you'll see an actual copy of "Stephen Stills" (released in 1970) in the glove compartment of his Cadillac at the airport.

You know, the scene where a barely restrained detective behaves as if he really wants to wring someone's neck. I mean, if looks could kill....

Oh well,"love the one you're with", eh? HAHAHAHAHAHA

And if you're wondering which album, I found this:

Frank- Bravo! You got it!! That thud you just heard was me fallin' out of my seat. One aspect of Columbo that I love is that he seems to enjoy music-especially classical.

Just as a bit of trivia, IIRC there was an AM classical station in LA in the 70's and I believe it was KFAC 1230 which also had an FM station at 92.3.

Woops . . . could've used that as an upcoming quiz LOL
