Yeah they had loads of hits in Canada, I meant more underrated in a legacy sense given just how many of them there were. Perhaps it's because they didn't have a "classic" lineup that continued to tour year after year like, say Aerosmith, or that they didn't do a big reunion tour like the Guess Who did in the early '00s, I dunno. I just feel like given the depth of their catalog, and their hits, that they should enjoy a higher profile.
Oh, and Say Hello is a fantastic song! I think one of the things I like about April Wine is that their sound continued to evolve, and very quickly too, a lot like Rush did between the late '70s and early '80s, embracing new styles and production techniques. Weeping Widow, I Like to Rock, Sign of the Gypsy Queen, Say Hello, all very different from each other, but each is incredibly catchy in its own right.
