Elvis and CCR

What, if any, are the best Elvis recordings on CD? Also, any good LIVE Creedence Clearwater out there? I once heard CCR live on the radio and it sounded great, but it wasn't what any of the live recordings that I find. Anyone?
My 5 favorite Elvis CD's that offer the best sound & performances are: 30 #1 Hits; From Elvis in Memphis; Tomorrow is a Long Time; 68 Comeback Special; Elvis 56. I thought that CCR had only one live album ... unless it's a Festival Recording.

I have found two CCR live recordings, unless they are the same recording with two different titles. However, I now remember that the live recording I heard on the radio was Creedence at Woodstock, but I have not seen it for sale anywhere.
