Neat old photographs from the past

The first photograph has "Glenda Dancing" written on the back and appears to be taken at an event hosted by a radio station by the sign on the wall behind them. The sign says 97.9 megacycles and the host is standing in front of large professional microphone.
The second photograph has "Chuckie 3 1/2 years old, Glenda 11 months" and mother is trying to ride her on the handlebars of the old tricycle. It also looks like the neighborhood is still under development at the time with excavated standing dirt piles in background.
The last two have no writing but are nice old photos of baby in galvanized wash tub, and two children in old wagon.
