A memorial service for Donna Summer was held Wednesday afternoon in Nashville.
Among the 400 guests rumored to attend included Lionel Richie, Aretha Franklin, Stevie Wonder, Elton John and Barbara Streisand.
The funeral was scheduled to begin at 2 p.m. at Christ Presbyterian Church on Old Hickory Boulevard in Forest Hills but delayed due to traffic in the area.
According to several reports, Michael W. Smith and Stevie Wonder, among other guests, were stuck in traffic due to paving project in the area.
Nashville's News 2 spoke with Summer's biographer before the ceremony who spoke fondly of the legendary performer.
"Donna was a wonderful woman, who was a force to be reckoned with. She changed music and was a good family woman and good Christian. She will be missed," Mark Eliot said.
Gospel singer Natalie Grant and David Foster were scheduled to perform at the service.
Summer, known by many as the Queen of Disco, gained prominence during the disco era of the 1970s. Her pulsing anthems such as "Last Dance," "Love to Love You Baby" and "Bad Girls" became the soundtrack for a glittery age of sex, drugs, dance and flashy clothes.
Her sound was a mix of genres, and helped her earn Grammy Awards in the dance, rock, R&B and inspirational categories.
Summer released her last album, "Crayons," in 2008. She also performed on "American Idol" that year with its top female contestants.
She died last Thursday after a battle with lung cancer. She was 63 years old.
