Never saw them in 1988 but intrigued and surprised by their stage on the MOR tour particularly Alex's drum set and solo with the rising platforms. All of a sudden out of the blue he decided to copy KISS and Motley Crue.
The stage was very sleek that year kind of a cool surprise to see the drum solo. His kit was indeed a little extra special that year. I'm guessing they wanted to do something extra since being a large stadium bill with the other acts. Only tour to my knowledge he did this.
