The Blues Brothers Band are coming to town

A Facebook sidebar ad informs me the Blues Brothers Band is coming to town. Unfortunately, it's in south London on a Saturday evening in the middle of summer: I'm not going to be able to get to it unless I spend Shabbos somewhere close. How much do I want to hear them? Well, there's only two members of the group who go back to Blues Brothers days, I don't think Dan Aykroyd will be performing with them, they'll probably be doing their own material (if the album of theirs I have is anything to go by) rather than the songs they did with the Blues Brothers, and I got to see the official 'A Tribute to the Blues Brothers' in Edinburgh fifteen years ago, so probably not that much.
