"On the road again" from Canned Heat I think, has no guitars in it (this is just 
from memory). Off the top of my head, I thought it will be fun to try 
and tab the harmonica bits - and here they are.
They sound pretty good to me but they aren't 100% correct


Title:  On The Road Again 
Artist:  Canned Heat
Album: "Boogie with Canned Heat" (1967)

Intro: (well this is on a guitar - also that sound like an electric 
razor is going in the background)

B-----------------------------------------------------------------12------------------------
G------------------------------------------------12-----------------------------------------
D--------------------------------12---------------------------------------------------------

E----12-------------------------------------------------------------------------------------

Then try this..

G---7---7---7---7---7---7---7/2----2--------7---7---7----7--------------------7-
D-------------------------------------------------------------------------------
A-------------------------------------------------------------------------------
E-------------------------------------------------------------------------------

where 7/2 means slide from fret 7 down to fret 2 &  7b8r7 means play fret 7, 
bend to tone of fret 8 and then release back to tone of fret 7.


this bit can be used at the end of some of the lyrics  (call it riff #3)

Lyrics: (please correct them if there some weird ones as this is off the top of my 
head)

Well my soul started crying but I'm out on the road again
On the road again  (play riff #3 over this line)
Well my soul started crying but I'm out on the road again
On the road again   (again play riff #3 over this line)
I ain't got no woman just to call my special friend  (now play riff#3)

You know the first time I travelled out in the rain and snow
In the rain and snow  (play riff #3 over this line)
You know the first time I travelled out in the rain and snow
In the rain and snow  (play riff #3 over this line)
I didn't have no ????? not even no place to go  (now play riff #3)

And my dear mama left me when I was quite young
When I was quite young  (play riff #3 over this line)
And my dear mama left me when I was quite young
When I was quite young  (Play riff #3 over this line)
She said "Lord have mercy on my wicked son"  (now play riff #3)

Little solo:

E--------5---7---9---10---13b14--/-8---------5---7---9---10---13b14--/--8---------
B--8~~------------------------------------8~~--------------------------------------8~~--
G-------------------------------------------------------------------------------------------
D-------------------------------------------------------------------------------------------
A-------------------------------------------------------------------------------------------
E--------------------------------------------------------------------------------------------

8~~ means let the note vibrate

13b14  / 8 means to play fret 13, bend the note to the tone of fret 
14, then keeping the tone of fret 14, slide down to fret 8

Take ???? mama please don't you cry no more
Don't you cry no more  (play riff #3 over this line)
Take ???? mama please don't you cry no more
Don't you cry no more  (play riff #3 over this line)
Cause it's soon one morning down the road I'm gone  (now play riff #3)

But I ain't going down that long and lonesome road
Al by myself  (play riff #3 over this)
But I ain't going down that long and lonesome road
All by myself  (play riff #3 over this)
I can't carry you baby gonna carry somebody else  (now play riff #3)

	that little solo comes up again now
