I went to see Triumph a few weeks ago, with April Wine opening. I think the tour may be over now, the last shows were in Boston (at least that is what it says on my concert shirt).
April Wine without Myles Goodwyn (RIP), was basically the band that had been touring with Myles, but with an officially endorsed new front man. It's not the same without Myles, but they got the crowd warmed up and singing along.
As for Triumph, they are/were a trio. The bassist, Mike, couldn't make it and they added two guys from The Conspirators, they are a great add. The additional drummer let Gil get out front and sing a few tunes, also synching two kits made a bonus add. As for Phil X, he replaced Rik way back when he left the band and filled in the high notes, as did Todd Kerns. The night I went, Phil X could not make it and Rik called up his old collaborator Steve Morse. That was a treat.
I am obviously a fan. The stands were full of us old guys n gals having a great time. We had good seats, about $270 total for both. Considering concert prices these days, not bad. Obviously more than my 1982 $18 stub.
