Keith Urban sang his hits for a sold-out Opry House audience Tuesday night, and the audience sang right back. After the CMA Entertainer of the Year nominee performed his first song of the night, “Sweet Thing,” fans who were gathered near the stage serenaded the superstar with “Happy Birthday” in honor of his birthday on Wednesday. Urban concluded his Opry set with “Making Memories of Us” and “Where the Blacktop Ends.” The superstar is scheduled to return to the Opry twice next month.
