Many people came to know the gospel group Dixie Hummingbirds when they backed up Paul Simon’s “Loves Me Like A Rock” in 1973.
It was a good thing for the group of course. Simon introduced them to a wider audience and presumably they made some money off the recording as well, including from their own version.
But this was a dynamic group with a vast and accomplished repertoire of its own. While the members have obviously changed, the group, having started in 1928, is nearly 100 years old. It’s less a group than an institution at this point.
