does anybody know if 18 and life by skid row is a good beginner-beginner song?

Yea, as long as you practice SLOW and with all your concentration it can be. As for the solo...try it, if it seems to hard just hold off on it for a while.
err its pretty simple except for maybe the solo... but anythings possible just keep at it... id say try it man you never know... its better than trying to learn little wing
even if you dont get it try it anyway. I find the songs I dont get and get frustrated with, if i go back a month or some time later its almost as if your sub concious figured it out for you.
