The Tulsa Boy Singers will perform their spring concert in downtown Tulsa tonight. Let's put it this way: If you enjoyed the singing at the recent royal wedding, you'll love the sounds that come from this boys' choir. The program includes both sacred and secular pieces. A reception follows the concert, where a Wall of Wine gives attendees the chance to win 20 bottles of wine for a $5 ticket. Tickets are $10 for adults, no charge for students.
