One Must Do What One Must Do, a pastiche road trip a la Ridiculous Theater and Bloolips, will close at La MaMa E.T.C. Nov. 21. The musical comedy by Christopher Tanner and Lance Cruce began performances Nov. 4.

As the century turns (the last century, that is), Khani, bandleader of Khani and the Kans and sometimes drag queen, finds himself playing in Hawaii where a local virgin is being offered to the volcano gods. Khani, sometimes the gentleman, offers himself instead, but is promptly spit back out. Exiled from the islands, he travels from Paris to China looking for love, fortune and meaning of life. Novelty songs featured in the score include "Becky From Babylon," "Cleopat-tara" and "I Want To Learn To Speak Hawaiian."

Cruce composed some of the original score with additional music by Andy Cohen and Vicky Cambell. The five person orchestra will feature Banjo, drums, flute, horn and, this being Hawaii, the ukulele.

Doing what they must do in the cast are Amy Coleman, Jason Howell, Berwick Haynes, Robert Molossi, Tanner (as Khani), Cruce and Kelly Webb.

Gary Hayes designed the set with Steven Hammel. Becky Hubbert designed the costumes and Brian Durham, the props. Tickets are $12 and available by calling (212) 475-7710. La MaMa E.T.C. is located at 74A East Fourth Street.
