I got married in Cuba last year with about 35 friends and family in attendance. That's the way to do it, I tell ya. No hassles, no worries, lots and lots of booze, and cheap, cheap, cheap, especially if you plan on a honeymoon anyways. You get to spend a full week (or 2) with all your buds, and evryone has a good, relaxed time.
The only problem is that you rely on the resort DJ for your tunes, so our first dance was some club bullshit, but no one really cared anyways because everyone was on holiday.
If I could have chosen my 'first song' it would definitely be from the 'Ella and Louis' album. Maybe "Dream a little dream of me" or "Cheek to Cheek". Those two sound like they've been in love for 50 years in every song on that album.
Sorry about the cheesy animation here, but the song is fantastic. Ella is just the greatest female vocalist of all time. Hands down.
