Some 273 unreleased songs by the Jackson Five, including a duet with Tina Turner, have been discovered among items in a warehouse full of memorabilia bought by a Toronto man.Howard Mann, who bought the items blindly, said he found masters to the unreleased Jackson tracks, which include recordings of Michael Jackson alone, duets with superstars and performances by the whole family. Much of it came from the 1975 CBS variety series featuring the whole family, reported Roger Friedman on Showbiz411.com.Mann claims he has sole rights to the recordings because, he said, they were made between the end of their Motown contract that summer and the beginning of one with Epic Records.
“The recordings belonged to the Jacksons. I bought them with the contents of the warehouse,” Mann says.Mann told Friedman gone into business–he tells me–with Katherine Jackson only, and not with Joseph Jackson. “My arrangements have nothing at all to do with Joe Jackson,” he said.
Mann and Katherine Jackson could be squaring off against the rest of the family over the Gloved One's legacy. Estate lawyer Howard Weitzman told TMZ he may go after Mann.Mann "may be using his relationship with Mrs. Jackson to infringe upon Michael Jackson's copyrights ... to the detriment of, among others, Michael's three kids," said Weitzman, adding that Mann has no right "to exploit any estate assets" and he will take "whatever action is necessary to prevent him from unlawfully profiting."


Howard Mann, the Toronto entrepreneur who bought a warehouse full of Jackson family paraphernalia, has a surprise for Michael Jackson fans and the singer’s estate.
He has the masters to 273 unreleased Jackson tracks. Some are Michael alone, some are duets with superstars like Tina Turner, and some are with the Jackson family.
A good chunk of them come from the 1975 CBS variety series featuring the whole family.
According to Mann, who seems to know his stuff, the Jacksons were between the end of their Motown contract that summer and the beginning of one with Epic Records.
“The recordings belonged to the Jacksons. I bought them with the contents of the warehouse,” Mann says.
Mann feels the recordings therefore do not belong to the Jackson estate, and he can release them any way he sees fit.
Meanwhile, Mann has gone into business–he tells me–with Katherine Jackson only, and not with Joseph Jackson. “My arrangements have nothing at all to do with Joe Jackson,” he says.
Mann also says he did not pay Katherine Jackson an advance for her book, “Never Can Say Goodbye.” Rather, they are business partners. It does seem that Mann has become The Man in the Jacksons’ life. But he says also his largesse is not responsible for the Jackson brothers reportedly all driving new cars.
“You’ll have to look elsewhere for that answer.” he says.
