He was in that production for four months before changing to the pre-Broadway workshop of Stephen Sondheim's Sunday in the Park with George, in which he acted alongside such stars as Bernadette Peters and Mandy Patinkin.

When he was eleven, Kane participated in the "Very Special Arts" festival, a series of benefit concerts for disabled children's charities, which gave him an opportunity to sing for then First Lady Nancy Reagan in the White House and at the Kennedy Center.

Kane has appeared in many commercials and programs such as Law & Order, One Life to Live, Guiding Light, Search for Tomorrow, and Plaza Sésamo.

He has also been a host on the Nickelodeon series Rated K Update and has been the assistant conductor of an interview program called Girl Talk.

He provided the singing voice of the character Aladdin, opposite Lea Salonga (Jasmine), in the 1992 film of the same name, as well as its sequels.
