Banshee Music, a division of New Berlin-based GMR Marketing, has combined with Recycled Paper Greetings to create a line of musical greeting cards. Pat McCurdy, a prolific songwriter, is one of several local musicians involved in creating 20-second ditties for the cards, which are now available at Target. "We're up and running," said Ryan Heuser, Banshee's operations director. "We've got seven cards out right now and more will be in the pipeline for Mother's Day and Father's Day."
