Is there a concert on Saturday morning?
Friday and Saturday nights have a Beatles tribute. Nothing Saturday morning.
There are around 4 each yr. They are focused on young children. The 1st this yr is Peter and the Wolf on Oct 1, 2016 beginning at 11. Doors open at 10. From 10 until11 children can enjoy the instrument petting zoo where they can play with the instruments.
They do occasionally have them during the week in the mornings. But none on weekends that I'm familiar with.
No just evenings. You can download their calendar from their website which can be accessed on tripadvisor.
