"Fleetwood Mac guitarist Lindsey Buckingham is apparently in good health after a scare during the group's recent tour. Buckingham collapsed after his morning shower July 29th in Philadelphia but played effectively that night, and was then brought to a local hospital for tests. A spinal tap taken there, followed by a plane ride to Washington D.C., left Buckingham in so much pain the band had to cancel shows in Pittsburgh and Cleveland. But he played strongly a few days later in Largo, Maryland, without resorting to a stage-side stool doctors had told him to rest on.
Lindsey accompanied Stevie Nicks, Mick Fleetwood and John McVie to Muddy Waters' gig in Washington, and Fleetwood drummed exuberantly with Waters' band for an hour after Muddy left the stage.
