The 38-year-old star of the ABC daytime soap opera "All My Children" will host a March 2 show at Town Hall to benefit the charity.
He is offering private dance lessons and the opportunity to perform on the benefit show, which will feature ABC Daytime soap stars and co-hosts of "The View." The auction opens Jan. 10 on the Web site www.broadwaycares.org.
Mathison competed for the disco ball trophy on "Dancing With the Stars" last season. He was booted off just before the semifinals.
The winning bidder will be flown to New York "for a few days' rehearsals, and I will teach them how to do a dance with myself," Mathison told Associated Press Television News in a recent interview.
"Really, there's a secret here that my dance partner from `Dancing With the Stars,' Edyta Sliwinska, is going to be coming in and really be the one to teach us, that's why I was smiling when I said that," he said.
