Get Madonna some throat douche, stat! Actually, don't break your neck, it won't make any difference according to Billy Joel.
The Piano Man took some time out during one of his many performances at Madison Square Garden to throw some shade at Madge's singing ability, which is kinda like shooting fish in a thimble. The crowd went wild all the same. In fact, the only thing missing was a genial 'badum-tish' from his session drummer.
For those of you unable to see TMZ's video, he treats himself to some throat love before saying "I saw Madonna use this once... it didn't help her much"
