That's Amore brass quintet

Jerry Lewis ostensibly forked over $30,000 of his own money to the songwriters to come up with something that woluld be a hit for his movie partner, Dean Martin. "That's Amore" did the job, becoming Martin's signature song. It first showed up in the 1953 Martin/Lewis comedy "The Caddy," for which it received an Oscar nomination for best oriiginal song. (It lost to Doris Day''s "Secret Love" from "Calamity Jane."
It has been covered countless times, by artists from Annette Funicello to the Wellington International Ukulele Orchestra.
This version leans on the trumpets for melody, with the others providing the "oom-pah-pah" and other support. Nothing fancy -- just fun, and a crowd pleaser.
