Former President Jimmy Carter and country singer Willie Nelson appeared at a fund-raiser for Habitat for Humanity, the home-building project Carter has been involved with since he left the White House.

Carter said Sunday that building homes for the poor is a concrete example of faith."Habitat gives us a chance to put our religious faith into practice more than anything I have ever seen, and to break down the chasm that sometimes exists between fortunate people like us on the one hand and people who have never had a decent home on the other," Carter told reporters before going to a $100-a-ticket reception.

Nelson also attended the reception before performing at an $11-a-ticket concert featuring gospel music.

Also attending were former first ladies Rosalyn Carter and Lady Bird Johnson, Kent Peterson, president of Austin Habitat for Humanity, and Austin Mayor Lee Cooke.

Habitat for Humanity is an ecumenical organization that builds homes and sells them to low-income families at no profit.
