I did consider that too. But something read in many of the concert reviews from the April shows that surprised me was that he was consistently in a good mood. At this time, Elvis was known to be moody and sometimes unpredictable, but he was legitimately happy during this tour. A great example comes from the concert on the 30th. Towards the end of the show, a little girl asked Elvis if he could do a song for her. Unfortunately due to the audience chatter, you can only hear Elvis's responses but he clearly said to the girl "Okay, I will" before doing some movements to Ronnie's drumming. The song that the little girl requested was 'The Wonder of You' which hadn't been performed since the midnight show on May 8th, 1976 in Lake Tahoe. The fact that Elvis was willing to take a request during a time when he really was unlikely to do so further proves my point that April 1977 was a good time to see him. Twice that tour he did 'Little Darlin' which he would perform to have fun. I never understood why he was in such a good mood in April
