A Goosebumps Moment With A Snag

Oh my God, today I heard the song that simply has to be the first dance at our wedding. It is just beautiful. Simple chords, beautiful but simplistic lyrics without any of the usual mushiness and the perfect tempo for a lovely, close, slow dance with my chap.
There's just one problem...
It hasn't actually been recorded anywhere and the only copy I have is a mobile phone recording from a live gig! And the quality is, quite simply, shocking.
Therefore, I feel I have just one option, given the man who wrote and performed this song (he's on the allowed list, needless to say) has only ever done it live this once and is highly unlikely ever to lay it down in a studio and certainly not before next June.
I am going to have to convince Da Boy to learn the chords and record it himself for us to dance to.
Now, there are two potential problems with this. One of them I'm fairly confident I can overcome but the other I'm not so sure about.
1) My fiance isn't that keen on the song himself, he thinks it's alright but nothing special.
2) He has informed me, in no uncertain terms, that there is no way in Hell he is going to dance to his own voice singing at our wedding.
The first one is the easy one. Da Boy really isn't that bothered what we do dance to as our first dance. We don't have "a song" for the two of us. The only one loved by us both is Jeff Buckley's version of Hallelujah but a song about love and life being a hollow sham probably isn't the most appropriate recording to start a new chapter of our lives together.
He won't take much convincing that my choice is the one because it's not a big deal to him. (No jokes about who wears the trousers please, it is Da Boy, whatever people might think!)
However, the second is a major obstacle. I have to point out here that Da Boy has a pretty damn good voice, is a fantastic guitar player and could, quite simply, record a beautiful version of this song standing on his head.
He wouldn't even need the guitar tab, he'd figure out all the chords after a couple of listens, set a copy of the words down in front of himself and be away on his digital mixer/recorder thingy. It is a standing joke in his band that the best guitarist and all round musician sits behind their drums!
No, the problem is that Da Boy absolutely hates being even close to the centre of attention. Anything which means people will be focusing on him in any way and he runs a mile. Hence why we're getting married abroad with just a few select guests of family and extremely close friends.
Not that he's lacking confidence or is particularly shy, he just likes to get on with things without any song and dance (no pun intended) or anybody paying attention. Even giving him a compliment or, if I'm feeling a bit sappy, telling him he's gorgeous makes him squirm in embarrassment.
I can see his point. Hearing your own voice, however lovely, filling your ears as you dance with your new wife for the first time would be a bit odd, especially for someone like Da Boy. So I suggested his band record the song for us to dance to.
And he very firmly shook his head and told me in no uncertain terms that Hell would freeze over before he danced to the sound of Buzzerd's voice either! Not that their singer is bad, on the contrary, he has a fantastic voice. The band boys just know each other far too well to have one of them sing a love song about another's relationship.
So, I'm a little bit stuck. I'm confident I can convince Da Boy to play the acoustic guitar bits, I just need to find a really good singer who doesn't know me or my fiance.
And that, ladies and gentlemen, is looking about as possible as Gordon Brown being able to dig this country out of the hole he and his cronies have dropped us into and filled in with concrete.
