A macabre entrepreneur combined the gimmickry of Jekyll and Hyde with one of those guided sightseeing tours of Manhattan, but instead of a double decker bus, patrons ride around in a hearse and rather than seeing landmarks, tourists are given the chance to visit locations where celebrities like Basquiat and Sid Vicious died. An uptown tour is coming soon, because it really wouldn’t be complete without seeing where John Lennon was murdered. |NYDN|
