ABBA

I went to an ABBA tribute concert in Paris.  I was pretty good.  A little hokey but overall good.  The theater, L'Olympia, was great and I expect to return there again.
The venue, the theater, is small but a great environment.  I'm sure there are several ABBA cover bands, but this one was ABBA Mania.  It was entertaining and I'd give them about a 7 or 7.5 out of 10.
