We're used to seeing Seth MacFarlane voicing musical numbers on his show Family Guy and for his movie Ted, but last night he stepped out of the sound booth and onto the stage of The Late Show With Stephen Colbert, where he performed the Frank Sinatra tune "The One I Love" off his new album No One Ever Tells You.

The album is filled with new arrangements of "old songs that have not been recorded to death," as MacFarlane explained in an interview on the show before his performance. Everything from the album art to the crooning musical style of the songs is meant to emulate the concept of Sinatra's 1955 album In The Wee Small Hours.

Perched on a stool center stage surrounded by a jazz ensemble and shined in the blue light of a '50s nightclub, MacFarlane smoothly sang the sad number originally titled "The One I Love Belongs To Somebody Else." He certainly embodied the style and swagger of Sinatra on stage as he sang about holding the cold hands of a lover whose heart is with another man. Watch the performance below.

MacFarlane has sang numerous times on his hit TV animated show Family Guy as he voices a number of the characters on the show. But, we've not seen him singing as himself too often, with the exceptions of his 2014 Christmas album Holiday For Swing! and the musical numbers for his movie A Million Ways To Die In The West.

In the interview he described the songs as having a new twist on them, however many, if not all, of the tracks fall squarely in Sinatra's classic '50s jazz style without too much variation. It seems there are still many fans that clamor for these old swing tunes given the success of a similar strategy implemented by Michael Bublé.
