Do family musicians have long careers because they have lots of ideas, or do they have lots of ideas because they've had long careers? While you're pondering the chicken-and-egg nature of the question, you can read this interview with Cathy Fink & Marcy Marxer, who might be exhibit A for consideration of the question. Over the course of more than 25 years of making music together full-time, they've got a lot of different plates spinning - albums, concerts, ukulele orchestras, creating musical curricula, and much more. Their latest endeavor is called Sing to Your Baby, a book/CD set designed to encourage parents, grandparents, and other caregiver to, er, sing to their babies. The idea that everyone should sing to and with their kids from the get-go is an important one to me, so I wanted to spend a few minutes chatting with Fink and Marxer about the project. And, as if to emphasize the duo's reach across the broad spectrum of family music, we started out chatting about one of kindie music's hot new groups, the Pop Ups, and ended by talking about living legend Ella Jenkins. Zooglobble: Good morning! Cathy Fink & Marcy Marxer: Good morning... so are you looking forward to going to Kindiefest? I am. You? We don't think we're going, but if plans change, we'll try... We're excited that the Pop Ups will be playing there. As am I... It was interesting to me the first time I listened to this random CD and found out that y'all were on one of the songs. Yes, and now one of the two, Jacob Stein, his father, Michael Stein, is the male vocalist on our album. Really? [Checks his copy of the book.] Wow. Hadn't made the connection. Cathy: Yes, he was in Country Current, the Navy's country band, when I first met him in the '70s. Later he performed and wrote songs for the Dinosaur Rock series. More recently, he became a cantor out in California. OK, so I usually start out interviews by asking people what their earliest musical memories are. In this particular case, I'm wondering what memories you have of music-making and singing by your parents.
