MINNEAPOLIS — Pop idol Bobby Vee, the boyish, grinning 1960s singer whose career was born when he took a Midwestern stage as a teenager to fill in after the 1959 plane crash that killed rock ‘n’ roll stars Buddy Holly, Ritchie Valens and J.P. “The Big Bopper” Richardson, has died. He was 73.

Vee, whose hits included the chart-topping “Take Good Care of My Baby” and who helped a young Bob Dylan get his start, died Monday of advanced Alzheimer’s disease, said his son, Jeff Velline. Vee was diagnosed with Alzheimer’s disease in 2011, and performed his last show that year.

Vee had been in memory care at The Wellstead of Rogers & Diamondcrest in Rogers, about 25 miles northwest of Minneapolis, for the past 13 months and in hospice care in recent weeks, his son said.

Vee died peacefully surrounded by family, Velline said, calling it “the end of a long hard road.”

He said his father was “a person who brought joy all over the world. That was his job.”
