I have an elegant solution for you. Drive to the gig, and therefore remain sober and in decent shape for tomorrow’s shenanigans. While you’re there, make sure that the Raleigh Boy necks back three hot chocolates (laced, optionally, with strong spirits), and you’ll be so busy trying to control him that you won’t even notice that you’re sober.
You’ll get home exhausted yet sober, sleep the sleep of a narcoleptic dormouse, and awake primed and ready for the day ahead. You should be able to pass the bill for damage onto the Raleigh Boy, as it’ll be him that causes it.
