Steve Ross, that former Washingtonian who performs through the end of June at the Ritz-Carlton Hotel, is a master pianist of the songs of Cole Porter and other greats of the 1930s and 1940s and all those great Broadway show tunes. Ross will soon, however, be going to New York City's famous Cafe Carlyle, the saloon that Bobby Short built. Ross grew up in Washington, graduated from Gonzaga High and attended Georgetown University. He previously played at the Algonquin Hotel's historic Oak Room in New York for four years. Before going to the Carlyle in September, Ross will be on a world tour that will include the Ritz in London. Don't be concerned about Short. He will still be fondling the keys at the Carlyle most of the time . . .
