VT, Your singing in a session is not the problem. The person who records and posts the recording is the one who would be in trouble.

If you are not being paid for your performance, you don't owe the royalty, the club owner does, as that is who would profit.

The main people they are going after are not people doing an interpretation of a song, it's the people using a recording of the original artist to make their video. Also, the people who buy a DVD, and then post the entire DVD on Youtube in little pieces. Both of which are theft.

As for showing off growing prowess on your instrument, why in the world would that have to be done with a copyrighted song when there are MILLIONS of PD songs to choose from?
