What’s wrong with Diana Krall?


Just wondering if anybody else saw Diana Krall on tour this past summer. I had been a very big fan and had previously seen her live years ago in San Francisco and Tampa/St. Pete. My recollection was that she was amazing in concert...she played flawlessly, she was engaging, and her ensemble was very tight. However, I took my wife to see her this past June in Memphis...man what a disappointment. First, they were 20 minutes late hitting the stage. Diana seemed like she was under some chemical influence...she mumbled her requisite bon mots to no one in particular, forgot lyrics to some songs (!), and basically took most of the night off, letting her bandmates do an extended jam session with lengthy solos on every song! Looking at customer reviews from her performances at other venues, this had apparently been going on for quite some time. Her whole set, including a halfhearted encore, was only about an hour. God, I hope she is ok and pulls herself together...what a terrible waste if she can’t.

This thread is, to me, worth as I realized that I do not have to hide anymore. I am not alone. I am on the list of people who are not impressed by Diana Krall, much less Norah Jones, and, if I may add, Elvis Costello (he is the biggest puzzle in that trio, to me, and I am afraid I am alone on this one). Those who like them should enjoy, a few of us who are not their biggest fans should skip. At the same time, we should be allowed to shrug our shoulders while quietly walking away.

To whoever mentioned Sid Vicious...thank you. His My Way, now you are talking about expression. It moves. It is quite unexpected to see him mentioned in a thread about Diana Krall, though.
Quickly googling "Diana Krall cancelling shows" brings links that reveal that she has cancelled in 2011, 2012, 2013, 2014, and 2018, at least. It seems it is always illness-related. Bad luck for a singer to have to cancel shows yearly (one was the whole tour, from what it seems).
Krall is considered a Jazz artist, a field not unfamiliar with substance abuse. I was an early fan of Costello (on his first album the band was San Francisco-based Clover, whose members included Huey Lewis on mouth harp), but have never liked The Attractions, and soon tired of Costello's out-of-control vocal vibrato.
Van Morrison not a great vocalist? What, you must be kidding.  Goodness he still has it! 
Van Morrison was already a great singer when the debut Them album was released in 1964. Listen to him on "Baby Please Don't Go" (a Big Joe Williams song from 1935!) and "Here Comes The Night" (written by Bert Berns). He, like Stevie Winwood, already sang like a man. Winwood was 16 years old when The Spencer Davis Group recorded "Gimme Some Lovin'" and "I'm A Man"!
