Winehouse 'puts medics on standby'

Amy Winehouse will perform at Glastonbury and Nelson Mandela's 90th Birthday Concert with medics on standby, say reports.

The singer is currently residing in a private hospital in London and is allegedly suffering from the lung condition emphysema.

However, Winehouse is determined not to let her fans down and wishes to perform both gigs this weekend, according to The Mirror.

Organisers of both events have apparently replaced requests for alcopops and vodka on her rider with jelly beans and Fruit Pastels.

Winehouse's backstage area will be equipped with a private hospital suite, massage bed and paramedics.
