I don't buy thhat Jim wanted to make amends without more information. Maybe if he had lived longer, but he was quickly distracted from family with his success. and he never showed any outward signs that he had any inetrest in his family any more. Maybe he was into Sinatra, since he started out crooning his songs, which may have been because Sinatra is what he grew up liustening to?  Now that you mention it, there's a strong resemblance btwn Jim's and Frank's singing style.  Most of my knowledge about Jim comes from McGowan.
