If you want to welcome Michael Nutter to the mayor's office on Jan. 7, you can shake his hand for free, or party with the man for fifty bucks.

Events announced by Nutter's inaugural committee yesterday have a decidedly populist flavor, with no black-tie galas or political fundraisers, and the only insider's event being a small reception for sponsors.

Inaugural events planned for Jan. 7, a Monday, include:

* An interfaith prayer service at 9:30 a.m. at the Cathedral Basilica of Ss. Peter and Paul, 18th Street and the Benjamin Franklin Parkway. It's open to the public.

* The swearing-in of Nutter and other officials elected in November at the Academy of Music, Broad and Locust, at 10.am. Tickets are distributed privately by officeholders. The event likely will be broadcast on radio and television, with details to be announced.

* A City Hall open house from 4 to 8 p.m. The public is invited to shake Nutter's hand in a reception line at the north portal of City Hall and to enjoy refreshments in a tent at the courtyard.

* A "Philadelphia Realized" party at the Cruise Ship Terminal at the Navy Yard, from 8 p.m. to midnight. This is the main inaugural bash, with Philly neighborhood-themed food and entertainment.

"The venue holds 2,000, and we really want people to come," said inaugural spokeswoman Jennifer Crandall. "This is a celebration for everybody, and that's why we made the ticket price reasonably affordable."

Tickets are available for $50 through Upstages ticketing agency at the Prince Music Theater, 1412 Chestnut St. The phone number is 215-569-9700.

Also, Nutter will attend a mentorship luncheon with students and mentors aimed at encouraging more people from the business community to get involved with young people. *
