This makes me laugh. I like to laugh. For those of you too lazy to click the link, it's to the "Legion of Rock Stars," a group of, er, musicians, who listen to music on noise-blocking headphones and play along to rock standards, recording their output. Some of them sound better than the originals.
It has reminded me of an idea I'd love to put into practice, if only I weren't so lazy: headphone karaoke. Participants would would don headphones attached to a music emitting device, the output of which the audience would not hear, and sing along to their favorite songs. Much beer would be required, I believe. Somebody organize this and invite me. There would be much rejoicing.
Thanks to .:DataWhat?:. for the link.
