Wedding music?

can i do 2 different songs like canon in d and then the wedding march or do i just pick one?
TIA

most do 2.... one for the bridal party and then something different for you.

i am doing a lot of various prelude music for guests as they come in, one song for my mom, one for BP and then one for me!!! (FYI: i am psycho about the music... it's one of the most important parts of the ceremony for me!)
