I forget how to do blue clickies and I dont't have the time just now but if you go here https://www.youtube.com/watch?v=gNJ5Sl-x5t8 you can hear the pipe tune. Ignoring the normal pipe repeats for the second part and the first couple of notes ONLY at the beginning, there's no denying the melody is the same as what is normally sung for the Freedom Call All Ye, albeit the tempo.
