Neil Diamond.Somehow, his American anthem “Sweet Caroline” has become the fight song of the Three Lions throughout their improbable UEFA Euro 2020 finals run this summer.It all started with Wembley Stadium DJ Tony Parry, who had a “gut” instinct to play the song after England’s 2-0 shutout of Germany in the round of 16, he told talkSPORT.Since then, fans have adopted the song as their own and have been belting it out across the nation.
