Yes, without any doubt! The perception of Elvis in the 70's is usually as a washed up overweight Vegas act. The Garden shows prove that he was far from that and that he was still slim (although starting to put some weight on in the midsection, but not much to really notice) and still rocking. He still had passion and cared about his appearance and his performances on stage. He was more of a serious business-first entertainer and giving the public their money's worth and less cutting up and cracking jokes and screwing up songs. Albeit, he wasn't heavily medicated during those Garden shows as he would be starting in 73. The Garden shows are also flawless, or close to perfect as you're going to get with an Elvis concert and featured no throwaway performances. He also opened the set with that's All Right, which was not his normal opener at that time as he was by then using See See Rider as the opening number.
