Pretty sure this was Cheap Trick's album where they did the inevitable dalliance with outside writing that had good results for a lot of bands. I suppose in THEORY it worked here, since this song was a hit, but like a lot of bands that tried this, it eventually worked against them and their sales were never the same. But my lasting memory of Cheap Trick is this. While I can point to individual sets by bands at a concert being better, the best concert, in terms of quality delivered by both the opener and the headliner, I ever saw was REO Speedwagon with Cheap Trick opening in the mid-80s. You had two bands that grew up in the 70s playing live constantly, and it showed, because I've never seen both bands on a show quite engage the audience like that. I've seen better openers and better headliners, but that show still holds the record for complete show quality from start to finish.
