Elvis and The Sweet Inspirations onstage: Date needed

Hi all, can anyone help me date the above photo of Elvis with The Sweet Inspirations & Kathy Westmoreland? Sorry it's not very good quality, but it's all I have. And if anyone knows who the photographer was, please say so. Many thanks.

Feb 21st, 1977

Wow, that was fast, Kenny. Less than two minutes after I posted. I really appreciate it. I've got a few more pics of the Sweets. Not sure if the dates are correct, but I'll post what I have. Let me know if I am right or wrong.




August 4, 1970, Elvis and the Sweets rehearse at the International

This is a long shot, but I'll try...could the below photo be the Sweet Inspirations backstage at an Elvis show in Las Vegas? Judging by their hairstyles, sometime after August 1970...
