One was a benefit for the USS Arizona Memorial in 1961.
MoJo actually knew that one. I found it either at Elvis.com or imdb.com!!
Right!! March 25 of 1961 finds Elvis at the Bloch Arena at Pearl Harbor. His performance and support raises money and awareness which enables the USS Arizona Memorial to be completed the following year. This will be Elvis’ last live, non-movie performance until his 1968 television special. Elvis will remain in Hawaii thru mid-April filming Blue Hawaii. When the soundtrack album debuts in October of 1961, it sells so well that it becomes second only to GI Blues as the biggest album of Elvis’ career on the Billboard charts.
