Duff embarked on a four-week concert tour in the U.S. from November to early December 2003. The song "Anywhere But Here" was included on the soundtrack of the film "A Cinderella Story"; Duff promoted the film and "Metamorphosis" with a series of television appearances in July 2004, including one on ABC's "Good Morning America". She performed before roughly 7,000 people, breaking a "Good Morning America" audience record. In the same period she embarked on a U.S. summer tour, during which she performed a one-hour set that included "Metamorphosis" tracks, covers of The Go-Go's' "Our Lips Are Sealed" and The Who's "My Generation", and previously unheard material from "Hilary Duff". Haylie Duff was the opening act on the tour, which ran for thirty-six dates and sold well in major arenas ; "Pollstar" editor-in-chief said that there was "a real positive buzz about ticket sales for Hilary's show". The tour was involved with the charity Kids with a Cause, of which Duff was a charter member in 1999; it sponsored a "Food for a Friend" drive and encouraged attendees to bring canned food to each tour venue, where the cans were collected and distributed across shelters in each city through which Duff toured. By early August 2004, enough food had been amassed to feed more than 12,000 children. The success of the tour was credited with helping keep the teen pop market alive in the tour circuit, and for being one of the "bright spots" in a slow concert season.
