Aut cum scuto aut in scuto
Been there and it's true that if you stand in the center of that circle and speak in a low voice the people in the upper parts can hear you clearly.
I've been there too. X2
I saw Zeppelin and the Eagles there! 🤘🏻
I sang there with a chorus on tour and then sang duet with an Opera professional touring with us, on that spot. It was an outstanding time for me.
