That's Diggy Liggy Lo, originally written by Terry Clement and recorded by the Clement Brothers.

nice complete answer, thanks!

I just listen again the tune, it looks like a PUSH song isn't it?

It is normally played in the push, I believe.

I think this is a typical push song. You could play it in the pull, but then you miss a few notes, and have to cover that up by using replacing notes.
And, in the pull, you will need a backing with the proper chords instead of your own basses to make it sound good. But it will be easier to sing! (in G or A)
