...........until his 1968 "Comeback Special" and his 1973 "Aloha From Hawaii" TV shows. Between 1968 and 1979 Elvis had 23 Top 10 hits on either the Pop, Country or AC charts.
The only thing I remember from that period was people remarking how fat he had become. My wife and her girlfriend went to his Richmond, VA performance in 1974 (I think) and she had the same comment. She did like his performance but never bought his records or listened to Elvis at home.
