It Was So Good While It Lasted is a 1950 jazz pop vocal tune by Nat King Cole and his Trio. It was released as a 10-inch shellac single on Capitol Records (818) with Bang Bang Boogie as the B-side. The A-side, written by Andy Ackers and Ruth Poll, features an orchestral arrangement conducted by Pete Rugolo, with Nat King Cole on piano and vocals, plus Joe Comfort on bass, Irving Ashby on guitar, and congas by Jack Costanzo. The track showcases the light, stylish Nat King Cole Trio sound of the era with a sophisticated backing. The lyrics reminisce about a relationship that felt wonderful while it lasted. It has later appeared on Nat King Cole Trio compilations such as The Complete Capitol Recordings of The Nat King Cole Trio.
