The band - in replica wear from the 1800s - performed music made popular during the Civil War-era, as part of the A.K. Smiley Public Library's annual Library Days celebration.
The annual event - which drew an estimated 100 to 200 people to the library - featured a variety of activities for all ages, including a weekend-long scavenger hunt that kicked things off Friday morning.
Those who completed the hunt were to be featured on the library's website after the game concluded Monday.
On Saturday, a variety of activities were planned for the four-hour event, which began with a presentation of historic films about Redlands with freshly popped popcorn available for the taking.
Children were invited to color candles and other candy-like features to add on a 3D paper birthday cake to celebrate the city's 125th anniversary.
A reading of the Redlands book "Two Girls in the Kite" was an added draw for children, which was followed by a sneak preview of a book on early Redlands photographers by historians Ann Cordy Deegan and Maria Carrillo, who also is the library's associate archivist.
The book - which, Carrillo said, will be available in December - features images pulled from the archives of the Smiley Library.
Proceeds made from book sales will benefit the library, said its director, Don McCue.
This year's event was made possible through a donation from Esri, McCue added, and was themed around the city's quasquicentennial and the 40th anniversary of the Friends of the A.K. Smiley Public Library.
"The people of Esri have been very supportive of the library and think this is a jewel for the community. I agree - obviously," said McCue. "They're the ones who sparked it. During Larry Burgess' last year - my predecessor - they came up with the idea of doing something to celebrate the library and to maybe encourage a type of patron that we normally don't get."
Every year, the library hosts a Family Day celebration in October. But Library Days has a goal of reaching a more adult community, those interested in doing a game themed around a library or seeing some films about Redlands and its community.
"It's just another opportunity to say, `Hey, come down to the library' and enjoy yourself,"' McCue said.
