I suggest that you listen to the song again. The key of the Dean Martin version is in Eb (that's the key of the YouTube link that you have provided).
The chart that I've posted follows exactly the same structure as that version (you can sync the iReal pro player with it to check).
If you're not familiar with the standard music convention regarding repeat symbols (Segno, Da Capo, Coda and so on, you can find the relevant information about it in this forum (or also on the internet, wikipedia and so on)
Cheers!
