A great way to become familiar with the form of a song is to use a play-along recording of it. There are many play along recordings available which feature a rhythm section but no melody instrument. Many of them contain either standard songs or progressions which are very much like particular songs. You can watch the melody and chord progression in a book as you listen to the recording, and then play the melody of the song along with the rhythm section. Once you are comfortable doing that, you can start improvising solos over the form until you are comfortable with it. By the time you can do this, you are ready to play the song with other musicians.
