Kings Of Leon drummer Nathan Followill spent Wednesday (04May11) in the dentist's chair as he underwent a root canal.
The rocker told fans of his operation in a post on Twitter.com as he prepared.
He wrote, "Good morning. Up early 4 my root canal, yay. Nothing like hiking with a swollen jaw and laughing gas in the veins. See y'all in lala land."
Followill posted a photo of himself wearing a gas mask on Twitter.com hours later as he prepared to go under anaesthetic for the operation.
