The Gospel Coalition

"In the more than twenty years since the group disbanded, they each recorded prolifically and each had his share of hits.  Some of their songs -- most notably Lennon's 'Imagine' -- have taken on lives of their own.  But when the Beatles gave up their collective persona, they also gave up their pervasive influence."
