<P> The pilot 's opening and ending songs were two similar Calypso - styled tracks written by John Williams and performed by Sherwood Schwartz impersonating singer Sir Lancelot . The lyrics of both were quite different from those of the TV series and the pilot 's opening theme song was longer . The short scenes during this initial music include Gilligan taking the Howells ' luggage to the boat before cast - off and Gilligan attempting to give a cup of coffee to the Skipper during the storm that would ultimately maroon the boat . </P>
