I don't care about other musician's sex lives, and they don't care about mine. I care about their music, and am honored if they care about mine. Keeping in mind that I like most types of music, I think Manilow is great in his genre of soft, melodic pop.
I always assumed he was gay, and thought he came out long ago. I have no opinion about his personal life, but I think his music is just AWFUL. My opinion only, of course.
