Phillip Phillips, the least-surprising winner in the history of “American Idol,” has been added to the list of network pluggers appearing on PBS’s “A Capitol Fourth” broadcast from the Mall.

Phil2 will be making his first live post-“Idol” appearance on the annual July 4 PBS special, performing “Home” — the least awful “American Idol” Winner Treacle Tune ever.

Phil2 hasn’t performed since the show’s finale last month. He’s been recovering from kidney surgery since shortly after he beat Jessica Sanchez to become the latest Scruffy White Guy with Guitar to take the Fox show’s top prize.

NBC also will be well-represented on the broadcast, with appearances from “Smash” actress Megan Hilty and “The Voice” Season 1 winner, Javier Colon. ABC’s “Dancing With the Stars” host Tom Bergeron is hosting this year’s “Capitol Fourth.”

Even Turner Classic Movies is getting a plug: This year’s “Capitol Fourth” will feature a musical tribute to Gene Kelly, including a medley of songs from “Singin’ in the Rain” and “An American in Paris” — eight days before TCM throws its “TCM Presents ‘Singin’ in the Rain’ 60th Anniversary Event,’ in which the remastered classic will be screened at nearly 500 theaters across the country, and about two weeks before TCM-parent Warner Bros. releases the “ ‘Singin’ in the Rain’ 60th anniversary” three-disc limited and numbered gift set.
