OK, more 60's: Jules Styne and Bob Merrill penned this "special love song" in 30 minutes in '62 for the stage version of "Funny Girl"('64) starring Barbra Streisand (like buttah, I'm getting a little verklempt, talk amongst yourselves...). It almost didn't make the script until Streisand finally belted it out on stage and the rest is Broadway history. It became her signature song and her 1st Top 40 hit, peaking at #5. Styne and Merrill were Tony nominated for it. Streisand shared the '68 Best Actress Oscar with Katharine Hepburn ("The Lion In Winter") for her role in the film version. Covered by Dionne, Aretha, Ella and Perry, among many others. The Supremes' version featured Florence on lead vocals - one of their very few recordings to do so.
Yesterday's answer: "Be Bop A Lula" by Gene Vincent.
