“Where is the Wonder” is from 1965's My Name is Barbra album and was written by the songwriting team Dion McGregor and Mike Barr. As written on their site, here is how Streisand came to sing their song:

In 1962 Barr hustled himself down to the studio of The Today Show when he heard that his favorite young singer, Barbra Streisand, would be appearing on the live TV program that very morning. He caught up with her and her manager, Marty Erlichman, at the elevator, where he handed her the lead sheets to three of their recent songs. Streisand looked them over and responded favorably to one of them, “Where Is The Wonder," on the spot. But it took a year before Erlichman called to say that Streisand was ready to publish and record “Where Is The Wonder," and at that only if the team accepts a contract granting them half of the already publisher-friendly standard minimum. According to Chandler Warren, the attorney Barr and McGregor hired to negotiate the deal, “Erlichman said, ‘We've gots lots of songs. If you want her to sing your fine song, you'll sign the contract. If you don't, we'll get another song.'” They signed the contract.



As for the B-side of this Streisand single, “My Man” is the Fanny Brice standard that was first sung by Streisand on her My Name is Barbra television show, and was later sung for the Funny Girl movie.
