So lots of sun damage over the years. I loved his songs as a kid and bought his best of Manilow album in late 70s. But I have lost any respect for him staying in the closet for decades as others fought the gay marriage battle. And then when allowed he secretly gets married to his long term companion. And then reluctantly admits to being gay in 2015 when the marriage is revealed.
As for harmony, 20 years is a long time to gestate a show although some successful shows have taken longer. Look at the hottest tv show on the planet is squid game and the director/writer said he wrote it 20 years ago. Maybe manilow has made the proper changes to improve harmony. Looking at the interview, I feel he wants it to be a large part of his legacy.
