I don't meant to throw water on the very romantic fire, but I would advise you to proceed with caution. He does sound like a nice guy, but drunken marriage proposals are generally not the basis for a sound relationship
When you get the chance (if distance no longer becomes an issue) by all means date the guy, but proceed slowly and with all due caution. My first boyfriend was also a romantic musician. I'm not married to him. Long story for another day, but bottom line, I would advise you to keep a level head, which you seem to be doing.
If nothing else, it's a GREAT story!
