Singing along to 'Crocodile Rock' helped Biden as a young, single dad

WASHINGTON – As a young father, Joe Biden had a commuting ritual with his sons. When driving Hunter and Beau to school, the three of them would sing Elton John’s “Crocodile Rock” as loud as possible.

Decades later, when Beau was dying of brain cancer and unable to communicate, that song again helped Biden connect with his son.
