"I have been hunting for records by the Ivy League Trio.   Saw them perform at the Platters circa 1960's in Cadillac, Michigan.   Have been a fan ever since. I have three records that I have transfered to CD, but quality is not good.   Is anyone aware of whether they are out on commercial CD's yet.   This is a great group with interesting harmony and chord changes.   Interested in any knowledge about the performers and what they are currently doing?"

Most of them aren't doing much. Yeah, you guessed it.
Norris O'Neill died a while ago, as did Bev Galloway.
I'm not too sure about Bob Hider (appropriate last name, then).
Galloway was on the two Coral albums, then replaced by Ronn Langford for the brilliant Poe folk song album Ronn is still with us. He founded Masterdrive.com

You can hear a sample of the Trio's Poe album here:

The Trio issued a few singles that don't appear on any album, (I'm Just a Country Boy" "Sailors Women") which are for compleatists only.

Norris and Bob were part of The Bitter End Singers for a while. Sample song:
