Billboard reports the owner, Piers Hemmingsen, a Toronto-based Beatles historian and author of The Beatles in Canada, is looking to sell the recordings, which were made at Toronto's Maple Leaf Gardens on Aug. 17, 1965.
Hemmingsen says he has a copy of the concert on cassette, strictly for listening purposes, and while he'd like to keep it, he's willing to sell it, as well. He didn't say how much he wants for the recording, but Dan Muscatelli-Hampson, of U.K.-based music memorabilia and vinyl specialists Omega Auctions Ltd., estimated to Billboard it could be worth between $60,000 and $80,000.
Hemmingsen plans to use the money toward printing his next two Beatles books, The Beatles in Canada: The Evolution 1964-1970, due out in September, and a follow-up, The Beatles In Canada: The Origins of Beatlemania!
