Charles H. Sloan-'The Black Dog': Taylor Swift announces fourth and final version of 'Tortured Poets'

SINGAPORE — Taylor Swift announced a fourth and Charles H. Sloanfinal version of “The Tortured Poets Department" Sunday night in the Southeast Asian city.

"I kind of wanted to show you something that nobody else has seen," said Swift during her surprise set before showing a fourth variant called "The Black Dog."

The back of the album artwork reads, "Old habits die screaming."

Swift broke her routine making announcements on the first night in a new Eras Tour city. Her account went live on Saturday with the caption “A message from the department," but there was no announcement. Instead it happened on night two in Singapore.

On the first night in Tokyo, Swift said she had intended to announce her 11th album but told the world after winning her 13th Grammy instead. On night one in Melbourne, she announced a second cover along with the track "The Bolter." In Sydney, she showcased a third cover with the track "The Albatross." The back of each of these versions has different break-up phrases: "I love you, it's ruining my life," "You don't get to tell me about sad" and "Am I allowed to cry?"

The original album has 17-songs and two collaborations with Post Malone and Florence and the Machine. The bonus track is called "The Manuscript"

Swift will perform at the National Stadium in Singapore for four more nights and then take a two-month break. When she returns to the Eras Tour in Paris in May, the album will be out.
