This is a stunning performance done by Masterpiece in the 2013 semi-finals that I transcribed. I've listened to this tune (arranged by Aaron Dale) hundreds of times on repeat just to hear the chord on the word "froze." Something about second inversion dominant chords in a barbershop style is truly mesmerizing!
This version of "Oh, Susana" was arranged by Aaron Dale.
-I had trouble finding a direct link to purchase the sheet music for this arrangement but on his website, there is a link to learning tracks. Additionally, you might possibly be able to email him through the contact form on his website to buy the sheet music directly.
