Music fans are being given the chance to own a unique piece of rock memorabilia belonging to Cream bassist Jack Bruce in return for helping to raise funds for a children’s charity.

Next Tuesday, a selection of personal items once belonging to the legendary bassist, including instruments, handwritten lyrics and clothing, will go under the hammer at Sotheby’s.

Bruce, who formed the supergroup with Ginger Baker and Eric Clapton, lived near Sudbury until his death, aged 71, last October.

A regular fundraiser for East Anglia’s Children’s Hospices (EACH), the Scottish-born musician’s generosity will live on through the donation of proceeds from next week’s London sale, which could raise more than £160,000 for the charity.

The 36 items include one of Bruce’s trademark patterned shirts, worn on German television in 1971 and expected to fetch between £800 and £1,200.

Autographed lyrics to Politician and one of their most famous songs, White Room, are meanwhile estimated to raise anything from £5,000 to £7,000.

The sale’s showpiece item, however, is a Warwick Thumb bass guitar thought to be worth at least £80,000 – and possibly even as much as £100,000.

Described as Bruce’s favourite bass, it was played at the band’s induction to the Rock and Roll Hall of Fame in 1993, on the recording of his last album, Silver Rails, on tour with Ringo Starr and his All-Starr Band, and at the Cream reunion concerts in 2005.

Among other lots are a snakeskin waistcoat, purple velvet jacket, a Hammond organ and draft lyrics to five songs, including Sunshine of Your Love, penned by Clapton, Bruce and his writing partner, Pete Brown.

Camilla Haycock, EACH development manager, said: “We are thrilled and honoured that Jack’s family have chosen to continue to support EACH with funds from this Sotherby’s auction and special memorial concert.

“Jack was a great supporter of EACH for many years and it is lovely to know that his wishes were for people to continue to support us.”

Since his death, Bruce’s family has continued to raise money for the charity, organising a sell-out ‘Sunshine of Your Love’ tribute concert to celebrate his life and work on Saturday, October 24 at the Roundhouse in London, featuring artists including Ginger Baker and Joss Stone, with all proceeds going to EACH.

The auction will begin at 2.30pm on Tuesday, September 29. All items in the sale are listed at sothebys.com/en/auctions/2015/rock-pop-l15414.html.
