I enjoy Norah Jones' music and was pleased when I learned she was coming to Wichita. So, Kathleen and I bought tickets and were looking forward to the evening. Curtain was 8pm yesterday.
At 7:55 the house announcer did the usual "turn off your cellphones" announcement and ended with "Norah will be out momentarily." At 8:01, the lights came down and a young woman walked out on stage...but it wasn't Norah. It was (in my world) the dreaded unannounced opening act. She performed for 30 minutes. Then, the roadies came out and reset the stage (after solo vocalist/guitarist) for 30 minutes! Finally, at 9:07, out came Norah.
While I didn't care for the opening act, it wouldn't have mattered if it was Eric Clapton. Concert promoters should list the performers and the times. In my opinion, it is rude and disrespectful of the audience's time for the main act to keep everyone waiting for more than an hour.
If you want an example of doing it right, go see Frankie Valli and the Four Seasons. They arrive on stage at the appointed time and perform for an hour and fifty minutes...without a break! Frankie is an old time performer (at age 75) with far more on-stage energy and enthusiasm than Ms. Jones.
UPDATE: Here is the man himself singing "Sherry" at the Westbury Music Fair in October, 2009.
