Another world class group of studio musicians was The Wrecking Crew. This was a group of musicians in Los Angeles who played on everything that was seen on TV, in the movies, TV shows such as the Oscar awards, you name it, they played on it. If you were listening to radio or went to the movies between 1952 and 1989, you heard the music of the Wrecking Crew.
The most recorded guitarist in history was Tommy Tedesco, who was nicknamed the Czar of L.A. based recording. He played on everything from Ozzie and Harriet, the Monkees, the Beach Boys to Frank Sinatra, classical music, anything.
Other members of the Crew were Dennis Budimer, Lee Rittenaur, Hal Blaine, Mitch Holder, Tim May, and several others. These were also the members of bands who played on the TV Games shows when the music came on for a commercial break or at the beginning and end of the show, and this included The Tonight Show Starring Johnny Carson.
