I loved your story about how you folks handled Frank and Ali in high school. It reminds me of something I read a while back about research on kids who went to magnet schools for music and how they fared in the real world afterward. There were only two factors deemed to be significant in the difference between those who were successful and those who were less so. Not talent as such, but (a) the involvement of parents in their education and (b) number of hours practiced.
As folks say here in Australia, ‘Good on you’.
