what i do is exactly what the tab states. I CONSTANTLY play hammer offs of the notes i have to strech. I suggest during the next show of the simpsons or something else, u just sit there, watch and continue to u strech with pull offs for at least the full 30 minutes. As i stated earlier for "are u gonna go my way" it took me a couple days to strech using the method i just told you with pull offs. Pulls offs keep the strength of your strech up as you have to keep constant pressure on the other fingers. Next you have to learn to strech your fingers quickly enough to play the faster songs. Basically comes with practice and time but remember it can be done.
