Well I would say there are several favorite moments and they are reflected in music history,
1 , Elvis 1956 rca major hit heartbreak hotel. drew a lot attention and record sales 1 million in short time. Was the nations eye opener that someone special in music has taken it to whole new level. Then followed string of #1 hits. And then even movies, even the Arny could bot stop Elvis popularity. While the movies where ok. NO movie star can or done what Elvis did all 33 movies NEVER lost money.
But He has said and I as a fan agree he was at his best doing live concerts, and when he was finally done with his obligations with movie contracts. He wanted the to show the people and fans he had a lot to offer talent , then the moves he was told to do or else. AND the 1968 Elvis special Show he was back Big Time! and while I think his peal concert was the Aloha Hawaii concert of 1973 was the best the peak of the Elvis, He still hung in there doing many great concerts breaking attendance records sales records. And when prior and after any time Elvis performed in Las Vegas It was sold out and people came from all over the world to see he in LAs vegas. He combine Country, with R&B and his own unique style and it was rock an roll, , he love gospel as well, he was very generous to countless charitys . To this day Graceland Is the most visted location outside of the whitehouse. A poor boy with who was bless with many talents, the best voice , style, looks became a major influence to many future artist Beatles and countless groups and singers. To this say Elvis sold more records than any single performer in history! and even in death, He is still the biggest money maker in history, Last year alone Elvis estate made ove $50,000,00 fifthy million dollars. Not bad from a boy born in a 2 room shack poor as one can be. and yet reach the heights that biggest record seller of all time. 33 movies none ever loss money and he made millions on each movie. performed concert in 4 years over 1,000 which is was major cause of death. to much tale pills to sleep Elvis 80,000 fans out their , take this so to do show. . unlike everyday folk can;t call in sick. when your entertainer like that with people waiting to see concerts some 2 a night. There never will be another Elvis. Like John Lennon of beatles said , Before Elvis there was nothing happening in Music! He truly was a one of a kind, Best singer, great concerts, Generous and kind to charitys , friends . Elvis was and is one of a kind! I sure answered your question and went on to do a little bio on this great singer/entertainer.
