Seamless Wedding Aisle Song Mix

I am wanting to mix 2 tracks together for my wedding aisle song. 1 track (wash piano rendition) for my bridesmaids, and 2nd track (what dreams are made of piano version) for myself as the bride.
I am wanting approx. the first 1:00 ish, to the first 1:45 ish of 'wash' before having a polished finish for this song that transitions monthly to what dreams are made of. I think I want the bridal entrance music at the start of 'What dreams are made of' cut out and for the track to just start at the start of the song. Happy to be guided by yourselves as to where and how to edit and merge the tracks for the most seamless finish. Thank you
