The LA Tonight Show Orchestra, under Severinsen, was the greatest big band ever put together. Every member was a first class studio musician before being invited to play.
The trumpet section there included John Audino and Conte Candoli in addition to Doc and Snooky Young. I can't place the fourth member. Any one of them could have played lead in any big band. Steve Marcus on tenor sax was another monster player, and Tommy Newsome, for all the ribbing he took because of his oatmeal personality, was a fine musician and a world class arranger. He wrote the majority of the band's charts.
You'll never see another group of musicians of that caliber assembled again
