Last year I went to see Uli Jon Roth in concert for the first time ever, and probably the last.
For those who don't know, he is a German guitar player who was in the Scorpions back in the 1970s. My main gripe was that he did not come on stage with his band until 9.15pm. Before then we had just one support act, which lasted only around half an hour. This was on a weeknight; I had work the next day, and so I was not prepared to stay till the very end of the concert. I enjoyed what I saw of the concert, but next time Herr Roth comes to town I will pass on buying a ticket.
Last night I went to see a Thin Lizzy tribute band - a long set with no support act. The doors opened at 6.30pm, and I arrived shortly before 7pm. I was then a bit miffed to find out that the band was not due on stage until 7.30. In the end they came on stage at 7.50pm.
Again it was a weeknight, and I had work the next day, and so I did not stay till the bitter end. I enjoyed the concert, but all the same I do resent them coming on stage twenty minutes late. Next time they are in town I might go to see them again, but I am not sure.
