Anyone who paid for college the traditional way (scholarships, work-study, parental support) will roll their eyes at this self-described ''Novel of Sex, Theft, Friendship & Musical Theater.'' But those with incredibly active imaginations and a willingness to believe that high school students regularly engage in three-ways will appreciate How I Paid For College's outlandish mid-'80s tale. Edward Zanni dreams of attending NYC's prestigious Juilliard, but Daddy won't cough up 10 grand a year in tuition. So Edward resorts to forgery, money laundering, a priest costume, and numerous trips to a gay piano bar. Thank goodness he's headed for the stage. This drama queen wouldn't be comfortable anywhere else.
