TAB REQUEST: What child is this

There's a guitar tab out there, but I'm not sure how to transpose it to bass properly and I'm assuming that there are people here that could do it in seconds, or at least know the location of a bass tab for this awesome Christmas song.

<shove> :-(

 

I give up, thanks anyway. :-(

 

I didn't find a good enough version, but I'll try again. Thanks for being the one responder, though.
