Will, read what was written! I am just putting the record straight!
George Sr - at the peak of his career - was never as big a star as George Jr.
Of course, George Jr benefitted tremendously from the arrival of "talking movies". On any particular night, George would have been seen by millions and millions of cinema goers.( George Sr, on the other hand, would been restricted to the number of people who could fit in to one theatre) And, of course, the record business was a lot more developed in George Jr's day.
   And, of course, the UKE.
   God knows how many people took up the uke because of George Jr ( his dad didn't play the uke), and how much money George made from the sale of ukes with George's name on them.
