The 1968 televised show AKA "The Comeback Special". Wearing an iconic black leather outfit and making his first live performance since 1961, Elvis gives a series of hour-long concerts that proves, after many years of going Hollywood, that he was still an incredible musician. The concerts get edited into the overall special - along with other staged performances - and the special is hailed as an instant classic.
Asked his opinion on Vietnam, Elvis is said to have replied, "Ma'am, I'm just an entertainer," and walked away. Talk about tact.
When the reporter then asked if more entertainers should follow his lead and not speak out about Vietnam, Elvis answered "No." And that's why Elvis was awesome.
This 1977 performance of "Unchained Melody," showing that Elvis had one of rock's most powerful voices right up till the end.
