Letta Mbulu singing ‘What’s
Wrong with Groovin’’ is one of the most glorious, defiant performances in the
history of pop. She challenges directly, demanding to know why she can’t be
left to be free, to live her life, to sing, to dance, and why the hell should
anyone try to put her down, keep her down, follow her around, spy on her, talk
about her, and try to stop her having fun and being herself.
