Spectators at the Canadian Open were treated to a bizarre spectacle yesterday as a rally was suddenly halted for the strangest of reasons.Jessica Pegula, seeded fourth, was taking on Iga Swiatek, the top seed, in the semi-final and after the former took the first set 6-4, we entered a crucial stage in the second. It was 6-6 in games, meaning a tiebreak was needed, and with the tiebreak score at 4-3 in favour of Pegula, the moment of hilarity struck.The game was halted mid-point as the song 'Cotton Eye Joe' by Rednex suddenly started playing over the speakers. The umpire very quickly stopped play as the crowd reacted in a bemused fashion, and the television announcer can be heard saying: "Oh wow. 'Cotton Eye Joe' just came on mid-rally... are we in Texas?," while the umpire can be heard telling the players to replay the point.It was certainly one way to liven up proceedings, and despite the inadvertent music break, Pegula was eventually able to put the distraction behind her and win the match 6-2, 6-7, 6-4.
