I'm completely new to Ewan and I just discovered him because I just recently became a Star Wars Fan. (Curse you Star Wars Rebels and Freddie Prinze Jr! I swore I'd never be a Star Wars Fan!) Originally I had watched A New Hope and up and I wanted to know so much about who Darth Vader was before he joined the Dark Side so I was so excited for the prequel trilogy. I thought "I'm a Han fan, I'm an Anakin fan, that's that." Nope. On my second time around, I watched the movies in so much more detail and I started noticing "Oh wow, look at how attractive Ewan is." "Man, he's a great actor." "He has beautiful eyes." "He's showing so much emotion in these scenes, he's so talented." And before I knew it, I was probably an even bigger Obi-Wan AND Ewan McGregor fan than my dad is!
Go to google, and type in youtube to mp3...any of the sites will be good to use and you can just put this link into it and then it will convert it to an mp3 file, and then it downloads which can go onto your iTunes. It's also completely free, and you do not have to sign up :) Hope this helps
