"I've chosen for 2017 to finish where I began, and where I was born, in the city of Manhattan, in New York, at BB Kings in just more than a few days. I intend to put the touring aspect of my life to rest," the former Partridge Family star said of ending his tour early.

"I'm one of the more fortunate human beings, let alone actors, songwriters, singers, musicians, producers, creators in that I’ve had a lifetime of living my dreams. Without you all I would have very little. I am now a very, very, very heart-full rich man," David continued.
