@A - Rail Body:The Lehigh Valley Sweet Adelines, an award-winning a cappella chorus with a 55-year history of performing in the region, will hold an open house Monday, June 2, at Saints Simon and Jude Church in Bethlehem, where they rehearse. The chorus is seeking female singers, 14 and older, of all levels of experience, to come and learn about an opportunity to sing onstage with them at their Sounds of Summer Concert July 16 at Allentown's West Park. Chorus Director Marilyn Block is both experienced and fun-loving. "This chorus is perfect for any woman who loves to sing and who wants to make friends, have fun and connect with her community," she says. "We have former and current church choir members, former high school glee club members, karaoke lovers and first-time singers who may have only sung in the shower previously. All of them fit right in." Arrive at the church , on the corner of Broad and Sixth streets at 7 p.m. June 2 to get a glimpse of this vibrant, growing chorus.
