This is the third in a series of posts that highlight classic rock songs which feature someone interesting sitting in on the recording session.  For this series I post the song on one day and identify who is sitting in the following day.  I hope you enjoy the concept and maybe learn some interesting music history in the process.

My selection for this post is a song called Old Times Good Times  from Stephen Stills self titled first solo album released in 1970.  Listen to the song and see if you can tell who was sitting in.

The answer will be posted tomorrow along with some additional background information.
