Sing and Dance

Legend and Kayla were mostly ignoring each other, playing with different toys across the room from one another, when Kayla started singing, at least I assume it was meant to be singing. Legend joined in right away and they sang a little non-sense song and danced together. They miraculously kept the same beat and bobbed the same way. Kayla added in the odd, random word, but mostly they said "Boo... Ba.. Beh" to 4/4 time and bobbed. It was kind of awesome and I wish I knew what song they were singing.
