'Internal sicknesses and problems' in KOL

Kings of Leon's cancelled US tour could cost up to $15m (€10.5m).

The band pulled out of 29 scheduled dates in North America earlier this week citing exhaustion and voice problems on the part of lead singer Caleb Followill, which could lead to their insurers, Lloyds of London, landing a bill running into tens of millions as promoters and concert venues claim for lost revenues.
