I don't know the years, but Neil Diamond puts on a great show. He has no warm up acts, and sings for hours. We went many times to his concerts and sat almost in the front row, and once in the front row.
There was a couple in our congregation that had a music store, and they sold concert tickets (long before Ticketmaster existed). She would always call me when Neil was coming and put aside tickets for us.
About 10 years ago, we saw Reba McIntyre, and she was great. Those tickets were an anniversary gift from friends who didn't know we weren't fans, but it was still a good show. She had a couple of warm up acts that were very good too. She had broken her leg shortly before the concert and performed in a motorized wheelchair. Very funny and she handled it great.
Last year we went to see The Brothers Cazimero, singers from Hawaii, and loved their show.
A friend of ours plays Hawaiian slack key guitar, and is friendly with many of the celebrated slack key artists, and when they come to Seattle, we go see them with him, and have met many of the greats. Raymond Kane, Ledward Kaapan, Owana Salazar, Keola Beamer, and more whose names aren't coming to me.
