Steve Bernstein (occasionally during live shows if accompanied with an orchestra).Maurice LaMarche (occasionally in some shows).The show returned to live theaters on August 28, 2021. In mid-March 2020 however, the tour was put on hiatus due to the COVID-19 pandemic as Paulsen and Rogel were originally going to perform in Dublin, Ireland. Among the songs will be an updated version of " Yakko's World" by Randy Rogel that includes a new verse to include nations that have been formed since the song's original airing, such as those from the break-up of the Soviet Union. Throughout the show, Paulsen and Rogel share behind the scenes secrets about the making of the series. Basically in most shows, only Paulsen and Rogel show up and perform with a piano (sometimes accompanied by Maurice LaMarche (the voice of the Brain) or a few others).
