Texas oil tycoon Clint Murchison was having a hard time bringing an NFL team to Dallas. He tried buying two teams, but the negotiations fell through. In 1958, Murchison heard that George Preston Marshall, owner of the Washington Commanders, was eager to sell the team. Just as the sale was about to be finalized, Marshall called for a change in terms. Murchison was outraged and cancelled the whole deal.
Around this time, Marshall had a falling out with the Commander band director, Barnee Breeskin. Breeskin had written the music to the Commanders fight song, now a staple at the stadium; additionally, Marshall's wife penned the lyrics to the song. Breeskin wanted revenge after the failed negotiations with Marshall. He approached Tom Webb, Murchison’s lawyer, and sold the rights for $2,500.
Murchison then decided to create his own team, with the support of NFL expansion committee chairman, George Halas. Halas decided to put the proposition of a Dallas franchise before the NFL owners, which needed to have unanimous approval in order to pass. The only owner against the proposal was George Preston Marshall. However, Marshall found out that Murchison owned the rights to Washington's fight song, so a deal was finally struck. If Marshall showed his approval of the Dallas franchise, Murchison would return the song. The Cowboys were then founded, and the legendary rivalry began.
