In 1964, The Beatles were selling out all the dates on their U.S. tour. But their Aug. 26 show at the Red Rocks Amphitheatre which would be the first rock n roll show ever at the iconic venue was a strange anomaly, with only 7,000 tickets being sold.
However, Beatlemania was clearly alive and well, as a 5,000-person crowd gathered at the hotel the band would be staying at, The Brown Palace, causing a massive traffic jam downtown.
Though the Red Rocks show might not have sold out, it did set a box office record for the open-air stadium.
