It's a bit difficult to search for songs when you only have a few words and the "Digitrad and Forum Search" is down again (normally, I'd recommend that you start there).  The song belongs to the group Professor Child called Our Goodman, and assigned number #274.  There are three versions in the DT database:

Five Nights Drunk (Our Goodman)
The Traveller (Our Goodman)
Shickered As He Could Be

There are also a number of past threads containing further discussion, background information and a number of other versions:

Seven Drunken Nights
Seven (?) Drunken Nights
LYR ADD: Seven drunken nights
5 Drunken Nights ?!?
