But it's not uncommon right now, probably due to the popularity of the newer song.
A little Layla would probably get sung at even more, and that hasn't stopped it from being extremely popular.
Before you criticize a man, walk a mile in his shoes. That way, when you criticize him, you're a mile away and you have his shoes!
