The actors in *The Fresh Beat Band* do sing in the show, but they don't always do all the singing themselves.
* The core actors (Yo Gabba Gabba! cast members) do sing most of their own songs in the series, but they are also joined by other professional singers.
* The Fresh Beat Band songs are often recorded with session singers who have strong vocal skills and can hit the notes perfectly. This is common practice in children's TV shows to ensure professional-sounding recordings.
So, while the actors sing some of the songs, the final recordings often feature a mix of their voices and those of professional singers. This helps ensure the music is enjoyable and engaging for both kids and adults!
