Notice

This version is based loosely on the soundtrack version but includes "Guitar Solo 1" from BTTF2 which isn't included on the soundtrack.
Also, I only included one verse as they're all the same.
Like the soundtrack, there's no wild abandon at the end (hey if you want to work that out be my guest)
It'll probably be too hard getting it to sound right on midi.
Maybe I'll try a bit later on but for now it ends with a fade.

I'm not too familiar with scale names but I think the solos are mostly in the minor pentatonic scale.
The most difficult parts are the position changes I think.
You can practice slowly and build it up to speed by changing the tempo at the beginning.
Half speed would be about 82bpm.
I copied this note for note off the cd up until the outro chorus which I copied and pasted from earlier parts.

Lyrics

Way down in Louisiana, down in New Orleans
Way back up in the woods among the evergreens
There stood a log cabin made of earth and wood
Where lived a country boy named Johnny B Goode
He never, ever learned to read or write so well
He could play the guitar just like he's ringin' a bell

CHORUS
Go, go!
Go Johnny, go go
Go Johnny, go go go
Go Johnny, go go
Go Johnny, go go go
Johnny B Goode

He used to carry his guitar in a gunny sack
Go sit beneath the trees by the railroad track
The engineers would see him sittin' in the shade
Strummin' to the rhythm that the driver made
People passing by, you know they'd stop and say
Oh my, that little country boy sure can play

CHORUS

Well, his momma told him one day you would be a man
And you will be the leader of a big old band
People going to come from miles around
To listen to you playin' 'til the sun goes down
And one day maybe your name gonna be in lights
Sayin' Johnny B Goode Tonight

OUT - CHORUS
END
