I don't think they are free but this site has the top three online sites. Check them out and see.
I know there are alot of videos of guitar lessons online you can watch and follow along with.
I have a website that you may like though. songsterr.com
They are based on tabs but what is interesting about the site is that they have a tab player with each instruments of the song playing together so that you can actually hear what you are trying to play, you can also mute any instrument as well. Great site! Hope this helps.
thanks! I really appreciate your help. I have checked all the links you sent me. Hope to master my skills and play like a rocker. Pray for my neighbours. Lol
