best vocal harmonies in rock

Wait! Why no mention of the Modernaires, The Four Freshmen, The Mills Brothers, The Ink Spots, The Meltones, or the Norman Luboff Choir? Oh, I forgot ... different era.

The thread's heading reads "best vocal harmonies in rock". If we're gonna relax the definition of rock, I'll add the great R & B and Girl Groups of the 1950's and 60's: The Ravens, Billy Ward & The Dominoes, The Clovers, The Drifters, The Platters, The Coasters, The Chantels (their "Maybe" is insanely great, as is Dave Edmunds' cover), The Shirelles, The Crystals, The Ronettes, The Staple Singers, The Persuasions, The Robins, The Swan Silvertones, dozens more. 

What about Ambrosia (David Pack as lead and...)?

2nd on Huey Lewis & The News

Tears for Fears (Especially when Oleta Adams performed with them)

Bruce Hornsby/Bonnie Raitt

James Taylor (with anybody)
And one that NOBODY mentioned:
The Guess Who (Road Food was a terrific album! Can someone hand me my cane or walker?)

Brad Delp, has some of the best vocal harmonies!

 97% of these 50-80’s singers were all “them”
not this current audiovocal, auto tune, computer help vocals tripe!!

  Phil mogg 
 Dave byron.

 30 others!

Has anyone mentioned The Mamas & Papas? I take them for granted until one of their songs comes on the radio. They were REALLY good!
