Songs and score for other home videos followed (such as Elmo's Potty Time), then the 2007 special Elmo's Christmas Countdown (as music director). Beginning with season 43, Toolajian began composing songs and cues for the show itself, including "Let's Find Out" (the regular song in "Murray's Science Experiments") and even a music cue just for Baby David. He also plays piano as part of the show's in-house band.
