English singer Amy Winehouse has apologised to SIR Elton John for cancelling one of her London gigs earlier this year (07), after the veteran rocker bought a ticket for the axed show. John and partner David Furnish bought tickets for the 8 March (07) concert at the Shepherds Bush Empire and were dismayed when Winehouse pulled the plug at the last minute, citing "unforeseen circumstances". Winehouse admits she was stunned when John's publicist issued a statement expressing the Rocket Man's disappointment. She says, "Sorry about that (Elton). There'll be a next time."
