Tuesday, July 5Where all them choral singers at? You know who you are. You're between gigs right now, and you're itchin' to sing a little Puccini this evening, like maybe the "Humming Chorus" from Madama Butterfly. Well, you're in luck, because the first of Webster University's three St. Louis Summer Sings programs is tonight. The Webster University Choral Society supplies the scores, which include the aforementioned Puccini, as well as Wagner's "Pilgrim's Chorus" and Verdi's "Brindisi." You just need to show up with the $10 admission fee, practice the scores a bit, enjoy some light refreshments and then perform the evening's program at 9:15 p.m. Registration opens at 7:10 p.m. at the Community Music School of Webster University (560 Trinity Avenue, University City; 314-968-7035).
