It only took five bids for the price of a Japanese seven-inch promo copy of Pink Floyd's final single with Roger Waters to sell for more than $3,000 on eBay.

'Not Now John,' featuring David Gilmour on vocals, and the Waters-sung B-side 'Your Possible Pasts,' both come from 1983's 'The Final Cut.' The song reached No. 7 on the mainstream-rock chart in the U.S. and went to No. 3 in the U.K.

The special promotional edition of the "Not Now John" single features a rare white CBS label.

The band was on the verge of splitting up by this point, since the LP is basically a Waters solo record. Founding keyboardist Richard Wright had been ousted during the album's difficult sessions. By the mid '80s, Gilmour and Waters were embroiled in a nasty legal battle over the rights to the Pink Floyd name.

Gilmour, along with Wright and drummer Nick Mason, prevailed. Since then, Waters has gone on to massive tours focusing on the classic Pink Floyd albums 'The Dark Side of the Moon' and 'The Wall.'
