Last week we brought you an auction of film memorabilia. Today, it’s one for the music buffs. More than 900 pieces of music history from the Hard Rock Café in New York are going to auction later this week. And there’s some pretty momentous pieces… Johnny Cash’s harmonica, Bono’s guitar, Elvis Presley’s extensive jewellery collection, a brick from the Cavern Club in Liverpool where The Beatles started out, Freddie Mercury’s handwritten lyrics, and clothes worn by Michael Jackson, Madonna, and Dolly Parton. But the biggest drawcard of the event is Eric Clapton’s 1968 Martin D-45 acoustic guitar that he played during the debut show of his band Derek and the Dominos. It’s expected to fetch up to US$500,000. Put a couple of hours aside, you can browse the virtual catalogue here.
