When Jonathan Robbins sings the "Welcome Song" that kicks off every session of morning classes at the Rock and Roll Kids Play Gym, he really gets into it, even though he's practically alone in his office. Swaying to his own beat while smiling and emoting a welcoming vibe, it's easy to imagine Robbins as the center of attention, even in a room full of toddlers.

When Jonathan, an Anthem resident and owner of the Anthem-area business, broke the song off about 30 seconds in to explain its origins, he was still just as exuberantly energetic.
