Master Going to California by Led Zeppelin

I'm following a tab by Oliver Elmes, on YouTube here: https://youtu.be/9WdT0C28aCs?si=ioc6DRrcfjeZ46EA I'm making some deliberate changes of my own. There are also some inconsistencies between the tab and what Oliver plays and I will point these out. I want to be able to play the song all the way through the exact same way each time, with vocals.
