Dr. Jacoby, you haven’t posted in this thread, but I found this amusing post of yours on FSM, from October 3, 2014, in a similar topic to this. I hope you don’t mind me reposting here (although these aren’t exclusively about following in their parent’s footsteps):
Ernest Gold had a son named Andrew, who had an uber-annoying 1976 US hit called “Lonely Boy.”
Jazz arranger and sometimes TV composer Marty Paich had a son named David, who was a member of the uber-annoying pop group Toto.
Dick Marx, pianist for Ken Nordine, whose word jazz albums might be considered soundtracks to the subconscious, had an uber-annoying son named Richard, who had dreadful pop career in the 1980s.
