Robert Plant plays birthday parties now! HA! He recently was invited to, and performed with a local band called "The Hayriders" at his ex-wife's 70th birthday party. They ripped through some Elvis classics for the crowds entertainment. Cool stuff!
Plant was married to Maureen from 1968 to 1983 and they had 3 children together, one of whom died in 1977 at the age of five. And here's a fun fact, Robert later dated Maureen's sister Shirley, and had a child with her in 1991. Here's to keeping it in the family.
