The musicians played on hits for artists including The Beach Boys, Johnny Cash, George Harrison, Bob Dylan, George Jones, The Supremes, Frank Sinatra and others.

Vince Gill paid tribute to Presley's Blue Moon Boys with his version of "That's All Right," while Frampton honored the Funk Brothers with his performance of "Signed, Sealed and Delivered."

"The music the funk brothers made was a real education and it's one I'm not done with yet," Frampton said. Funk Brothers drummer Uriel Jones was moved. "I've been choked up all day. All the great musicians up here; I'm just excited to be among them," he said.

The Nashville A-Team consists of Bradley, Ray Edenton, Charlie McCoy, Bob Moore, Hargus "Pig" Robbins and Jerry Kennedy; The Funk Brothers is Jones, Joe Messina, Eddie Willis and Bob Babbitt; The Wrecking Crew is Billy Strange, Don Randi, Larry Knechtel, Joe Osborn, Hal Blaine, Lyle Ritz, James Burton, Jim Horn and Mike Deasy; The Memphis Boys is Bobby Emmons, Bobby Wood, Gene Chrisman, Mike Leech and Reggie Young; The Tennessee Two is Marshall Grant and Bob Wooten, who replaced the late Luther Perkins; and The Blue Moon Boys is Scotty Moore and D.J. Fontana.

The nominees are chosen by other musicians rather than industry executives, with a new class of inductees expected each year.
