MIAMI (AP) - U2's Bono has long made headlines for his political and human rights efforts, and he didn't disappoint his Miami fans this week.

Bono gave a shout-out to Cuban dissident Oscar Eliseas Biscet during a concert Wednesday at the AmericanAirlines Arena.

Biscet is a doctor and former political prisoner on the communist island. President George Bush awarded Biscet the 2007 Presidential Medal of Freedom.

Bono mentioned Biscet during the song "Walk On," asking the audience to let everyone know in Cuba that Biscet "is special to us, and we are watching."

The mention was connected to an Amnesty International campaign and followed a recent meeting with Republican Florida Congressman Mario Diaz-Balart, who is Cuban-American.

Bono frequently mentions political prisoners during concerts, such as Myanmar's Aung San Suu Kyi.
