Please don't confuse "don't know lead singer" with "never heard of". I don't know the lead singer of the Bee Gees, either (though I'd probably get the last name).
Accept "mime" and "miming" for lip-synching? Also, it's a bit of a laugh building Luxor Casino like a pyramid, since there are no pyramids anywhere near Luxor. They must have thought "if it's Egyptian that's near enough"!
There are a couple very small pyramids in Deir el-Medina, where the people who built the Valley of Kings have their tombs, but I agree with your point!
