You know a relationship is at the three-year mark when one partner is picking out clothes for the other. Such is the case with Canuck pro golfer Craig Matthew and Mississauga-based EMI Music Canada. This year, Matthew will be wearing custom shirts with album covers from country music stars such as Tim McGraw, LeAnn Rhimes and Keith Urban while on the green. HMV is making it a threesome with its ‘Country Swing’ national campaign beginning June 20 and running for three weeks. The promo offers discounts on titles sported by Matthew. A pack of Acushnet golf balls will be added to each CD purchase.
