Because Manscaped’s “The Boys” ad song is a custom creation, it appears that unnamed studio professionals are responsible for its music and vocals. As such, unless more information about the song surfaces, its singer might have to be filed under “unsolved internet mystery” … for the time being, at least.
That being said, if you’re looking for similar music, it’s worth noting that the song bears considerable resemblance to The Teskey Brothers’ ballad “Forever You and Me.” The Australian band’s song is a bluesier, more mellow affair than the Manscaped song, and the vocals are obviously different — but there are enough similarities in tune, tone, and general vibe that fans of the ad’s song might at least want to check the group’s song out.
It’s easy to assume that a well-known song might yield better results than an original one, but crafting a song from scratch has produced some serious earworm ads before. For instance, Disney forced Michael Jordan’s “Be Like Mike” Gatorade commercial to create an original song when they charged too much for the use of “I Wanna Be Like You” from “The Jungle Book.” This resulted in an all-original pop song that fit the ad’s tone perfectly and made it an instant hit with fans.
