Best - Madonna, Blond Ambition. Wembley Stadium, July 1990.
Taking into account that Madonna was probably the biggest 'star' in the world at this point, we were very lucky to get tickets for a start. (Ahh, the days before t'internet).
It was a truly fantastic show. It had everything going for it. The songs she chose to sing were fantastic. I can't praise it highly enough.
Oh and by the time BA came to England, she had gotten rid of that weird ponytail she insisted on wearing, and she looked a whole lot better for it.
Worst, Madonna, The Girlie Show, Wembley Stadium, September 1993.
I was probably expecting too much after the outstanding BA Tour, but TGS was poor. Very poor.
A lot of the songs were changed beyond recognition, which was a massive shock. If you're at a Madonna show and she decides to sing Like A Virgin, you expect LAV. Not some weird re-mix that sounds nothing at all like the original.
Also, she performed too many songs from the 'Erotica' album, which (although time has changed many perceptions), it was nowhere in the league of Like A Prayer.
I remember a lot of people started leaving the venue before the concert had finished.
