"are you suggesting that every song sang should be an all in just like we did it last week?"

When did I ever suggest that?

One might hear a new song or a tune in a session and someone might say ..."Oh that's a nice song!"
Someone else might say "Yes that's one of Kara What's her name's".

So, your music is even more widely shared and, who knows, someone might even come to one of your gigs as a result?
