 The Shermans were brought onto the film by Walt Disney due to Disney's feeling that the interpretation was keeping too true to the Rudyard Kipling book.In a deliberate effort to keep the score "light", this song as well as the Sherman Brothers' other contributions generally concern darker subject matter than the accompanying music would suggest.In the case of "That's What Friends Are For", the vultures sing in the style of a barbershop quartet, making their song endearing to Mowgli - and that much more dangerous.
