My FH has been very laid back with the planning process and there has really been only one thing that he asked for which was to fly in with his GM's by chopper. So of course I said yes.
Everyone keeps saying 'he's going to steal your thunder!' which I think is a load of bulldust. To me, the day is about US not ME. So if FH would be stoked with flying in and it would make the day for him, then that makes me happy too. I get to spend a ridiculous amount on a dress and have everyone 'ooooh' and 'aaaaah' over me all day so why not let FH have his bit of fun right at the start.
I say if you are only concerned about the song because of what people will think.....stuff 'em. It's your day to celebrate and if you are happy to go with that song for the sake of FH then do it.
If not, then maybe make a compromise by having a fun song that's a little more traditional. AC/DC you shook me all night long or Queens another one bites the dust as jaynage said. Either way have fun and enjoy it!
BTW, our entrance song is the footrot flats theme 'Slice of Heaven' by Dave Dobbyn
