If you're one of your parents' 11 children and are looking for something rewarding and fun to do with your 10 brothers and sisters, there are actually a number of options to choose from. You could, for example, form a football team. Or a soccer team. Or a field-hockey team.

Or, you could do what the children of East Moline's Charles and Barbara Westbrook did: You could form your own band.

"We did all of it," says Delores Westbrook-Tingle of her and her siblings' ensemble the Westbrook Singers, who began performing together in 1975. "I mean, some of us just played instruments - we had a couple of drummers, keyboard players, a guitar, a bass guitar ... . So when we actually started, all 11 of us, we had all our musicians and the vocalists, as well." She laughs. "We were pretty much self-contained."

Nowadays, however, the official number of full-time Westbrook Singers stops at four; after seven performers either moved from the area or retired from the group, the current lineup consists of Delores, brother Gary, and sisters Brenda Westbrook-Lee and Cynthia Westbrook-Bryson. Yet given the gospel quartet's smooth, stirring vocals and harmonies that clearly come from lifetimes of practice together, no one who has heard the group in its numerous concert and festival sets, CDs, or televised specials for the Quad Cities TV station WQPT could argue that they're getting only four-11ths of a great thing.
