I did not know that Hibs, Aberdeen and Dundee United once played in a league over in the USA.
"After a series of exhibition games, the USA began playing on May 28 and got off to a good start. The Houston Stars attracted an opening crowd of 34,965. However subsequent attendances did not keep pace and the league finished with an average of 7,890 per game. Of the twelve teams, the Los Angeles Wolves, represented by Wolverhampton Wanderers and featuring Derek Dougan, the Cleveland Stokers, represented by Stoke City and featuring Gordon Banks, and the Washington Whips, represented by Aberdeen, emerged as the strongest sides. Roberto Boninsegna of Chicago Mustangs finished as the league's top scorer with 10 goals. The USA entered its playoff stage in July 1967. The Western Division champion Los Angeles Wolves, by the flip of a coin, won the right to host the championship game against the Eastern Division champion Washington Whips. The match drew 17,824 to Los Angeles Memorial Coliseum. The Wolves won the championship beating the Whips 6-5 after 36 minutes of extra-time. The wide-open final feature two hat-tricks, three penalties given (2 converted), four goals scored within a 4 minute period midway through the second half and each team scoring during (non-golden goal) extra time. The game was finally decided when Whips defender Ally Shewan scored an own goal shortly after the start of golden goal extra time"
