This song is probably in the DT but I can't find it -- I've forgotten the title, and none of the scraps of lyrics I've tried have turned up anything.

It's a cuckolded husband song, he asks his wife what some other man's horse is doing "where my horse ought to be". She calls him a blind drunk, and says, "Can't you plainly see, it's nothing but a milk cow, me mother gave to me." and his (chorus) is about how he's been all over the world, but "a bridle on a milk-cow, I never saw before." This goes on in a similar vein for several verses, ending up with his seeing someone else's head on his pillow, "where my head ought to be" and she claims it isn't a head, it's a cabbage. The end line is "a beard on a cabbage, I never saw before."

You'd think with this much information I'd be able to either find it in the DT or remember the title, but so far I've had no luck with either. Thanks.
