Canadian rockers the Trews are set to play the Town Ballroom this Friday night.  The group makes a swift return to the Western New York area after playing this past June at Artpark as a part of the venue's free Coors Light Wednesday Concert Series.  While Friday's show is not free(tickets are $20 in advance and $25 at the door), we have a way to get a couple free tickets.  The band pulled out two covers that evening at Artpark.  The first to tell us the name of both covers and the original artists gets the tickets.  Answers can be emailed here.  Good luck.
