I am walking down the aisle to "From This Moment" by Shania Twain. Do I need another song for the bridesmaids?

I only have one Bridesmaid and a Maid of Honour and a Ring Bearer walking down the aisle before my Father and I, do I need to have another song played for the other 3 people walking down the aisle? What is a good song for the guys to enter the ceremony? I was thinking the James Bond Theme by the London Symphony Orchestra. Is that tacky? Also looking for Father/Bride song and Mother/Groom song. Thanks for your help!
