You might have already finished your song using the information in Bob's links in the previous post, but we have just started a Guides blog and coincidentally a Coda one has just been published.

(Other helpful blogs will be posted from now on as we have time to produce them.)

Using this idea, one way would be to copy/paste the verse below (to make its form ABA) then add text DC al Coda at the last measure (bar) at the end of this second A section (which is your lead ride verse). This will tell the player to go to the beginning again then continue until the coda symbol, then jump to the coda itself (your ending measures).
Add a coda symbol (see the blog as there is a DC al Coda shown) at the last measure of the B section.
After your lead ride section, on the line below add in another coda symbol to indicate this is where the Coda starts, a left barline and any chords and barlines to create your measures needed to finish the ending.
