If you look for Harvest Home at  J C's Tunefinder  you'll find lots of entries; not tab, but a choice of abc, midi, or staff notation.  The tune (a hornpipe, though regrettably it is often played as a reel, which rather spoils it) is widely known in both Ireland and England; it's more likely to be an English than an Irish tune, but I don't have definitive information on that.  As with most dance tunes, there are no traditional lyrics.
