Chris Martin of Coldplay performed Saturday at the funeral for Beau Biden.
Also during the service, President Barack Obama remembered Beau Biden, the vice president's son, as a public servant who learned through early tragedy what mattered most and resolved to "live a life of meaning" that would lift up those around him.
"He was a scion of an incredible family who brushed away the possibility of privilege for the harder, better reward of earning his own way," Obama said. He described Beau Biden as a son, a father, a soldier and a politician who didn't cut corners in his efforts to serve his country and others.
The former Delaware attorney general died a week ago of brain cancer at age 46.
