Future Musician -- It's Written in the Stars!

Grandma and Grandpa are great patrons of the arts in San Francisco. With all their memberships and season passes, not to mention all the shows they attend, they are single handedly sustaining numerous city institutions. This patronage does not end with the symphony, the ballet, or art museum memberships. Actually it extends to your life, Rai.
Grandma and Grandpa are the generous donors behind your own budding musical career. They are responsible for those wonderful music classes that you've been taking. This early start on your musical career has been good for you, music class is a highlight of each week for you!
However, even without this early intervention, Grandpa tells us, Rai, that you're destined for musical greatness no matter what! Considering the great musicians that our family shares birthdays with, there is no way that you won't turn out a famous musician!
Rai: 4/22 shared with Glen Campbell and Peter Frampton
Maciej: 9/9 shared with Otis Redding
Kotaru: 10/13 shared with Paul Simon
Ashe: 11/3 shared with Adam Ant (who's that, you say?)
Even Ko, with his tiny little hands, but long fingers, is sure to share in that musical heritage!
