I really don't know which part in the song you're reffering to with the first few, but on the last.. you can slide, or play it with 4 fingers. I prefer 4 fingers..but hey its Yngwie, is he EVER going to use 4 fingers? Of course you have to move your hand at some point, but if you use all 4 fretting fingers I think its a lot easier (once you get used to it).
