Hi Carl ... Stan Irvin of the Sahara booked the Beatles before they came to America and on the Ed Sullivan Show .... everyone in Las Vegas laughed at him for booking this group. He could not give the tickets away for the Congo Room appearance .... then a few weeks later the Beatles were on CBS and the Ed Sullivan Show .... a big hit .... customers at the Sahara were now begging for tickets ... the Sahara had to rent the Las Vegas Convention Hall to Accommodate the guests ..... BEATLES INVADE LAS VEGAS!
