This is in E major, and there is some room for improvising, especially to fill in the long held out notes (~) and throwing in little rhythms.
The bass comes in at about 0:05.

This tab of course isn’t perfect, but I think it gives you a pretty good idea of how to play it. There are times when there are little trill things on the high e that I didn’t bother writing out, especially towards the end. if you listen to the song, you should get a good feel for the rhythm too, it swings a little bit.
