"Little Rabbit" - what do you know about this song?

I found tab for banjo in tabs section and I started to learn it. But I knnow nothing about this song... Maybe it has lyrics? Or maybe it's just a traditional bluegrass tune? Or maybe it was written by Tony Trishka because I saw he played it on youtube? I don't know and I can't find any information about this tune... Maybe you know something about it? It's just interesting for me, who is composer and other information, because I like rabbits)) Thank you)
