Ideas for my processional song

I really wanted to walk down the aisle to the across the universe version of "blackbird" but I cannot find an instrumental version. I don't like the beat to the actual Beatles version so I've come to the conclusion that I must make a new decision. 

Right now, I'm liking the idea of an instrumental version of a Panic! At The Disco song. 

Either

1. Northern Downpour
2. The End Of All Things
3. Collar Full
4. Always

If not, 

1. This I Promise You- NSYNC
2. I Do (Cherish You)- 98 degrees
3. Requiem on Water- Imperial Mammoth
4. Turning Page- Sleeping At Last
