When Nat , who lives in Lower Manhattan of New York City , was four years old , his father , jazz pianist Michael Wolff ( bandleader on '' The Arsenio Hall Show '' ) played Nat music , primarily jazz . One day , Michael overheard Nat teaching himself how to play major chords on the piano ; Nat told his father that they were his " proud chords . " After hearing the music of The Beatles , Nat became inspired and watched all the group 's films including '' Help ! . '' On the other hand . Alex discovered how to play the saxophone at the age of two and a half . As recalled by the boys ' mother , actress Polly Draper ( star on ABC 's '' Thirtysomething '' ) , Nat and Alex were infants when they arose from a bath proclaiming , " We 're the naked brothers band ! " After the September 11 attacks , six-year-old Nat composed the song " Firefighters " for a benefit he performed with his band , staged behind his Lower Manhattan apartment . Alex desired to be part of the concert , and so Nat created " a fake plastic saxophone " for him to play . The charity ended up raising over $ 45,000 and was donated to the children of the firefighters who were killed during the terrorist attacks . After the band 's charity concert , the band performed shows at Christmas parties and wedding ceremonies
