Growing up in a small town in Eastern Washington in the early 1970’s, I read a book I still remember. It’s a middle school targeted chapter book with a few line drawing illustrations. My copy was paperback. It features a father and son, the dad is a jazz musician / fan, I think they live in the Village - or at least someplace downtown NYC. Maybe there is some music that is played on the rooftop? Maybe parents are divorced? Published pre-1974.
I think this is ‘The Teddy Bear Habit’ by James Lincoln Collier!
Teddy Bear Habit, definitely. There’s also a sequel, called Rich and Famous.
(And if you liked that one, you should try Me, Cassie by Anita Feagles. It’s hard to find, but well worth it!)
I think you are right and you are more than E – Excellent, Energetic, Educated, Exciting! Thank you for your knowledge and for making my day.
