Lets play a fun game!!

Hopefully Elvis fans don't mind playing an Elvis game on here for fun. I have been listening to other 1970's songs lately and just wandering what Elvis's voice would have sounded like if he would have recorded some of these songs. Does anyone on here think that Elvis would have sounded good singing songs like Lying Eyes by the Eagles, or By the time i get to Phoenix by Glenn Campbell? Or even Whichata Lineman by Glenn Campbell? If anyone thinks of other songs Elvis would have sounded good at singing please posts on this thread thanks alot. Your Elvis friend Gerald!!
