Weaver is part of a group from St. John's Lutheran Church in Hagers-town that attends most of the Sunday concerts.
"I like any kind of music," he said. "The music, relaxation and fellowship."
Nancy Hopkins of Williamsport is part of the same church group, and said her son, Jackson Hopkins, 18, plays the French horn in the band. He has been with the band for three years and will attend Shepherd University in the fall to study music education.
Jackson's mother said he has gone to the park to listen to the band since he was a baby, and he enjoys playing with the group so much that part of the reason he chose a local college was so he could continue to participate.
William and Marquita Storms of Greencastle, Pa., said they attend most of the Sunday concerts.
The couple said they drove through a rainstorm to get to the performance.
"We took a chance that it would stop," Marquita Storms said. "I think it's great. They have a lot of great musicians up there."
Charley and Barb Ware of Hagerstown said they are friends with Sunday's soloist, Gregory Shook, who plays the oboe. Shook directs Hagerstown Choral Arts, with which her husband sings, Barb Ware said.
"We thoroughly enjoy the concerts," she said. "We've only missed one this season. We love the music."
Edward Knepper of Ringgold said he and his wife, Barbara Knepper, try to attend each of the performances. Most of the time they bring their grandson, Elijah Knepper, 9, of Hagerstown.
"This is one of the best-kept secrets in Hagerstown," Edward Knepper said.
