On the BBC morning programme a presenter asked Ulvaeus his secret for staying young looking. He replied "Running is good. Unless you're in the Boston marathon." A presenter immediately leapt in to point out the seriousness of the recent bombings, and in the British press Ulvaeus was accused of being tasteless and insensitive.
Ulvaeus says to Aftonbladet that "The worst part is if there's someone who thinks I really intentionally joked about it, and thought it was funny."
