That's a proper concern about Lionel Richie's health, and we're glad he's getting it checked out properly. Cancelling shows is never easy for an artist of his stature, but an irregular heartbeat is exactly the kind of thing you don't mess about with. The good news is that the legend is being proactive about it rather than trying to soldier on, and we'd much rather have him back in full health when he does return to touring. Hopefully he'll make a smooth recovery and get back to doing what he does best, because the world's not quite the same without his voice in it.
