Feb 11-13 David Cassidy w/ the Omaha Symphony Holland Performing Arts Center, 1200 Douglas St. Fri.-Sat. 8 p.m., Sunday 2 p.m., $15-$80, omahasymphony.org While some of us will be dreading the idea of Singles Awareness Day, others will be celebrating a weekend of love with one of the biggest heartthrobs of the 1970s. Known best as Keith Partridge of the Partridge Family, David Cassidy has enjoyed a long career as one of pop music’s golden boys and one of its longest running acts. He returns to Omaha backed by the Omaha Symphony to spread the love — no doubt including his hit single “I Think I Love You,” the best-selling record of 1971 that seems like it’s been on every love soundtrack since its release. Celebrate love with the sounds of yesteryear or as a great gift for the parents this Valentine’s Day weekend.
