Michael McCary

*Boyz II Men are marking the anniversary of their debut record, 1991’s “Cooleyhighharmony,” by recording old and new tracks for a retrospective record called “Twenty.”

But only group members Nathan Morris, Wanya Morris and Shawn Stockman are taking part in the project. McCary, who left the group in the early 2000s, was to return for the album, but it didn’t work out.

“We reached out to Michael to be on this record,” Nathan Morris told the New York Daily News, before explaining that McCary, in his view, didn’t want to put in the effort to reunite.

“Mike just completely got lazy,” according to Nathan Morris, who ended up recording the bass parts on top of his own.

“Twenty,” to be released Tuesday, finds the trio singing new songs as well as their classics – 10 of each.  They will also take the project on the road.  The “Twenty” tour will take them around the United States, Europe and Japan.
