premise: Live in Concert is the second live music video title by singer and actress Cher. Released by HBO in 1999, it contained footage from Cher's Do You Believe? Tour specials filmed at the MGM Grand Garden Arena in Paradise, Nevada in 1999. It featured tracks from the Gypsys, Tramps & Thieves album to the Believe album, alongside various covers. She has 7 costume changes by stylist Bob Mackie.
hypothesis: Live in Concert was released by HBO more than 1000 days ago.
reason: 1000 days is less than 3 years and it was released 20 years ago. It's difficult because 1000 days is an unusual way to measure time.
