Last night I happened to catch the last 10 minutes of the audience with Freddie Star show.
Freddie started singing Don't and to my surprise Freddie had the Jordanaires backing him.
I have never heard this version by Freddie before but I thought it's the best cover I have heard of an Elvis song.
I posted the same clip on YouTube here.
I hope it works.http://youtu.be/S25SV4yrWVg
