ELO, May 1978. I was 22. Cologne, Germany, on their "Out of the Blue and into Germany" tour) at the Sporthalle (which was an odd venue due to the fact that it was also used for cycling). 18 DM, as I recall (about $8-10). There's a cd out of the concert they played not long before that at the original Wembley stadium which has a very similar playlist. Big laser show too. Odd though the tricks memory plays on us, as I thought they opened with Turn to Stone, but the setlist shows otherwise. Got to see them again at Nationwide Arena last year, and they were really good, though I think only Jeff Lynne is left from that line up.
