As Seger Ellis sang in 1929, “To be in love . . . it’s simply marvelous,” and I think most would concur. Although there is a long tradition of songs describing heartbreak and sorrow, there are also the songs that praise monogamous devotion.
Here’s one, performed with an affectionate bounce (it was originally a waltz) by Dan Barrett, trombone; Rossano Sportiello, piano; Joel Forbes, dtring bass; Ricky Malichi, drums, at the 2017 Cleveland Classic Jazz Party, sadly the last of those wondrous gatherings.
And if you want to jocularly remark that the only boy and the only girl in the world a) hints at post-apocalyptic romance, or b) they would fall in love out of a lack of other amusements, I hope you’ll keep it to yourself and enjoy this swinging performance more than once.
May your happiness increase!
