They were a really good rock and roll band
They still are. They still average about 30 shows/year. Although Miles Goodwyn is the only original member of the band (Gerry Mercer sadly has stopped playing drums and is now in his late 70's), Brian Greenway is still in the band and he goes back to at least 1980. For a Canadian, April Wine (and Randy Bachman, of course) are a mainstay of summer festivals across the country. I saw them about 4 years ago and they still put on a great show.
