Till now other nations' national anthem has been played before 'Jana Gana Mana' in an ICC event. In any case, that is not the certainty. It has a straightforward rationale. It is that the facilitating country's national anthem is constantly played at the second. It is chosen by basic two different ways.
In the event that the game is played in Team A's home ground, at that point group An is the facilitating country and their song of devotion would be sung second.
In the event that the game is played between two teams A & B and team A is having preferred ODI positioning over team B. At that point group, B is the host, and group B's national anthem would be sung second. Group B's commander would likewise get an opportunity to turn the coin.
This often seen in a bilateral cricket series or any ICC cricket tournament which includes Champions Trophy, ICC World T-20 and ICC World Cup. Like any other sporting event at an international level national anthem is played.
