On 57 episodes of Saturday Night Live, by this site's count, the host was also that night's musical guest, and 47 people and acts have done both. Of those, 9 have done it more than once, and Justin Timberlake has done it most, with 3. Justin Timberlake is the one member of the Five-Timers Club among them.
What gets counted
A night counts here when the season page credits the same person or act as the host and as a musical guest. The rule, and the cases where it needs a ruling, are set out under hosts and musical guests in how this site counts. That page also sets this site's total beside the one Wikipedia's list of guests gives, and explains the night the two disagree about first: Paul Simon's, in October 1975, when the season page credits the music to other acts. A credit to a persona counts the persona, so Garth Brooks's night as Chris Gaines is not one of these either.
Two jobs on one night
Some of these nights belong to performers known for both jobs. In UPI's report of Donald Glover's episode in May 2018, he pulled double duty as host and musical entertainment, took on his Star Wars role of Lando Calrissian in a sketch, and later in the show performed a new song, "This Is America," as his musical alter ego, Childish Gambino.
Timothée Chalamet's booking for January 2025 came from the other direction, an actor taking the music slot. The Associated Press announcement had him as host and musical guest on his third stint as host, and noted that for A Complete Unknown he sang and learned to play the guitar and harmonica to play Bob Dylan.
For Lady Gaga, doing both in March 2025 fell in a release week. Stereogum noted that her album Mayhem had come out that Friday, that it was her fifth time as the show's musical guest, and that she performed "Abracadabra" and "Killah" live for the first time.
