Any good music must be an innovation.
In a sense, a hit belongs to the person who made it popular, but if a tune is good enough to attain tremendous success, then it certainly deserves more than one version, one treatment, one approach.
I'm not an intellectual composer.
I love doing concert music.
I did the Broadway album unfortunately in a year when there were no hits.
Well, thats the secret of commerciality, a simple style and you stick with it.
