A song

So I was trying to remember the old folk song that goes, 'Shoo, fly, don't bother me,' and all I can remember is that it's about telling a fly to go away. So what comes out, to a completely different folk-boogie tune, is:

Go, fly, don't come catch me 'cause I'm gone

Go, fly, don't come catch me 'cause I'm gone

Go, fly, don't come catch me 'cause I'm hiding out in the Tree

Go, fly, don't come catch me 'cause I'm gone
