If you do want Elvis then consider "Are You Lonesome Tonight" Its about 25.5 bars per minute which is s bit slow for MW. I speed it up a bit (29) and its great and popular.
You have not said the age of your friends which is important when asking for music suggestions.
Other tunes that provide both a music and dance experience:
Toni Wille and Benny Neyman- Oh, How I Miss You Tonight
Henry Mancini - Moon River
Cait Agus Sean - Flying
Mireille Mathieu _ La Derniere Valse (LastWaltz)
Henry Mancini - Charade
Cliff Richard & The Shadows - When The Girl In Your Arms Is The Girl In Your Heart
If they like rock music let's say under 60 then also:
Journey - Open Arms
Eagles - Take It To The Limit
I rarely use dance music - often not a music experience, may as well have two sticks tapping together. The music you hear in elevators! Like watching paint dry - boring!
I use the original exciting music and rearrange it.
