alas I cannot take the credit for that, it was one of the backdrop pictures - but I liked it a lot.
I did convert it to monochrome as I think it is very effective for pictures like this.
I am going to blog about the concert a little later...and there will be more pics on my blog...and there are already some on my Flickr site.
Here is a link if anyone wants to have a peek at them.
