The working lives of musicians and songwriters make it hard to build successful intimate relationships and enduring marriages. What are the odds when both partners are big music stars?

It’s surprising how many musician couples choose to make music together. The McCartneys, Don Bryant and Ann Peebles, June Carter and Johnny Cash. Debby Harry and Chris Stein, the Captain and Tennille.

There’s a long list, and while their personal relationships didn’t always last, these couples made some great music.
