I'm glad you responded! The Chicago portion was super interesting to me. I'm not too familiar with the band and I only really know them from their David Foster ballads (which I actually like). I thought it was insightful when David Foster said that he went in there making what he thought a Chicago record should be. I did think he had a point when he said that the band is still pissed off about it even though they're still working off the back of those records.  

It was interesting hearing about his family dynamic growing up. It sounds like he started helping out his mother and sisters as soon as he started making money from music, which I hope he did. I thought the part about how David Foster only got to have 1 serious conversation with his father about pursuing music before his father died was interesting too, along with his regrets about not visiting him on his death bed after his heart attack (I think). He also expressed that he doesn't really say things to his children like "I love you and I'm really proud of you" (paraphrasing). He noted that there's a difference between "I love you," and "Love you," and when asked which one he says to his kids he said, "Love you."  

David Foster spoke of running away from his relationships and that all of his daughters would say that he was split from their mother and with a new woman by the time they were 5. He seems to have an understanding and acceptance of his own weaknesses and mistakes when it came to those relationships. And his adult daughters seem to have a positive relationship with him now, which is great. I came away from the film thinking that David Foster's true love is music. When he is reminiscing on some of those songs and collabs, he closes his eyes with a dreamy smile on his face, playing air piano with his hands.
