First I better offer up my definition of a “harmony group,” which is any group that tends to privilege harmony over lead-and-support. That’s tricky. In rock and roll, lead and support groups almost always had formidable harmonies, even if they just amounted to Keith leaning into Mick’s mike. And, in fact, one of my two favorite rock and roll vocal arrangements (I’m leaving black and white gospel and bluegrass out of this) is Gladys Knight and the Pips’ “Midnight Train to Georgia” which is just about the definition of a lead and support group finishing each others’ breaths. My other favorite is the Byrds’ “Turn, Turn, Turn,” which is so purely harmonic it sounds like it couldn’t possibly have been “arranged” any more than breathing is.

With those for logical extremes, there’s a lot of room in between. I’d place the midpoint somewhere in the neighborhood of the Rascals’ “Good Lovin’,” which weaves a lot of fantastic ¬†and surprising harmonies into a classic lead and support structure. Start asking which sub-category the Rascals, or that record, fall in and we could be here all day.

So, to keep it simple, I’ll just list all the rock and roll aggregations I think of as being true harmony groups of the first order (no matter how many great leads they may have featured):

The Everly Brothers (from whom all else flows); the Fleetwoods; the Beach Boys; the Beatles; the Hollies; the Byrds; Simon and Garfunkel; the Mamas & the Papas; the 5th Dimension (at least until somebody figured out they could sell a lot more records by putting Marilyn McCoo out front); Spinners (a close call but I put them just this side of the divide); the Persuasions; ABBA; The Bangles.

That’s a nice baker’s dozen. I’m leaving out a lot. I’m counting Peter, Paul and Mary as folk. Doo wop is very confusing in this respect as is reggae. Groups as diverse as the Four Seasons, the Shangri-Las, the Jackson 5 or the Staple Singers (just to name a very few) had consistently fantastic harmonies, but were finally dominated by their principal lead singers. And a group like the Searchers made plenty of fine records without quite sustaining the heights of those I mentioned.

Still, even whittling the definition down to the bone, I’m left with Phil and Don, Gary Troxel, Brian and Carl; Paul and John; Allan Clarke; Gene Clark (with a nod to Roger McGuinn, who shared Sly Stone’s uncanny ability to be the dominant force in a group where he was far from the best singer); Paul and Artie; Denny and Cass; Marilyn and Billy; Bobby Smith and Philippe Wynne; Jerry Lawson; Agnetha and Frida; Susanna Hoffs and the Peterson sisters. (Update: Of course, I was bound to overlook a few. A day later, I already see the Impressions and the Turtles are inexcusably missing. Make ti a baker’s dozen plus two, then and my sincere apologies to Curtis and Howard and whoever else it will turn out I forgot. But it doesn’t change the final answer! 2nd Update: Also forgot the Bee Gees. Oh, yeah, them! Sorry Barry. Sorry Robin.)

If I had to pick a “greatest” I wouldn’t.Not even with a gun to my head. I’m a little thick but I’m not stupid.

As for a favorite?

Well, sometimes it’s easier than you think it will be.

You just have to think of a little test.

Like, who, of all those great singers, could make me listen to this tripe all the way through, every single time it ever came on the radio, just to hear a four line chorus which featured maybe your fiftieth best vocal?

You, Carl. Only you.

I’ve said it before, but there’s a piece of me that will never accept him being gone.
