Dismissed as a square by rock ’n’ rollers during the turbulent era of Tricky Dick Nixon, Lawrence Welk was the embodiment of silent-majority music. The prolific and popular band leader, accordionist and television show host created a bubbly brand of big band melodies that came to be known as champagne music. Spry and sentimental, his distinctive, easy listening mix of show tunes, polkas and novelty songs still doesn’t get the respect it deserves. On Sunday, May 15, Richmond Welk enthusiast Joe Enroughty and his crack band the Royal Virginians pop open a bottle of the man’s classics and vintage big band standards at Christ Ascension Episcopal Church. The 1930s-themed event features a spacious dance floor so you can cut a rug as the group time-machines its way through the oldies. The performance runs 7-9 p.m. with a free dance lesson at 6:30 p.m. Period attire is strongly suggested. Admission is $6. cachurch.net.
