McCartney had a great solo career. Lennon did OK and was killed just as he was coming back to the charts. Harrison and Starr had limited solo careers.
The Rolling Stones are a different story. They are still going.
Mick Jagger, Keith Richards and Charlie Watts are still in the band. Bill Wyman retired a couple of years ago. Brian Jones died in 1969. He was replaced by Ron Wood and Mick Taylor.
Bottom line: The Rolling Stones are the longest running band of the rock era.
