I randomly sing various song, I dont have to be listening to a song for it to get stuck in my head, so not to long ago I randomly started singing "i love to sing-a about the moon-a and the june-a and the spring-a" and i was cracking up to myself because I recall it being from a cartoon. Well after some youtubing i found it! It made my day to see it, I hope it does for you too.
