One of the first times Elvis trew his belt in the audience was during the show in Lubbock, Texas on November 8th, 1972. It was the original belt of the "Blue Nail".
In Aloha he trew his belt and cape in the audience and on June 30th, 1973 in Atlanta he gave away the cape and belt to a ten year old boy. It was the cape and belt from the "Phoenix" which is regarded as the most heavy and expensive of all.
After that he kept to giving away jewelry and an occasionally guitar.
