Why are there only three members in boyz ii men? There used to be four.

The original members of Boyz II Men were:

Wanya Morris (born Wanya Jermaine Morris on July 29, 1973 in Philadelphia, PA)
Shawn Stockman (born Shawn Patrick Stockman on September 26, 1972 in Philadelphia, PA)
Nathan Morris (born Nathan Bartholemew Morris on June 18, 1971 in Philadelphia, PA)
Michael McCary (born Michael Shawn McCary on December 16, 1971 in Philadelphia, Pa)

McCary had been suffering from a lingering back injury, stemming from scoliosis, and retired from the group in 2004, leaving the other three members to continue as a trio.

McCary appeared in the TV movie Miami Beach Ocean Drive Music Festival in 2011, and in the TV series Celebrity Poker Live in 2012.

Currently Boyz II Men are in Australia, their fourth tour in the country.
