Dave,
I don’t know of any specific songs where the entire melody falls within the pentatonic scale.
If I may throw a suggestion out there though, I would consider practicing your pentatonics while listening to a 12 bar blues, and improvising along with it.
Also, I’m not sure if you’re aware, but the three is flatted. (noticed you have 1,2,3,5,6). I can also provide a diagram with the five positions of the pentatonic scale, in the key of E, if you like.
I know I didn’t answer your specific question, but I thought I’d put some stuff out that may be helpful in working on the pentatonic scale.
Hope that helps you.
Jack
