Jay Sowers / The Natchez Democrat — Volunteers join Amanda Lamberti, center, a Summer Staff Music Leader with the World Changers initiative, in singing the World Changers theme song during a worship and music session at Parkway Baptist Church on Wednesday evening. Wednesday’s worship event was scheduled to be hosted on the bluff in downtown Natchez but was moved because of rain storms. Two hundred students from 10 churches across the South are in Natchez this week participating in the 23rd summer volunteer project, which focuses on revitalizing substandard housing area around the country.
