Leonid & Friends doing any of Chicago's catalogue. Check them out on youtube - out - frickin - standing!!! All songs note for note identical & perfect even though they may not even really know what the songs mean. Funny. They're all Russians but simply great artist citizens - nothing to do w/ crazy man Putin.
What is your favorite cover?
There are many great covers, such as Mr. Tambourine Man,by the Byrds. I'm curious about everyone's favorite.
