Stand By Me (riff and solo)

bass line: 

4 4 3 -3 4 4 4 -3 -3" -3" 3 -3" -3" -3" 3 -2" -2" -2" -3" 3 3 3 -3 4 4 3 -3 4 4

repeat for the whole song

If you can't do bends then here's the same bass line but without bends (you can also change between the two and play this in the chorus for example):

7 7 6 -7 7 7 7 -7 -6 -6 6 -6 -6 -6 6 -5 -5 -5 -6 6 6 6 -7 7 7 6 -7 7 7

solo:

7 -8 8 8 -8 7 7 -7 -6 -6 -7 -7 -6 5 4 -3" -3 4 -3 -7 -7 7
3 4 -4 5 6 7 -8 8 -8 7 7 -7 -6 -6 -7 -7 -6 5 4 -3" -3 4 -3 -3 4 

(some parts of the solo go too high/low for the harmonica so I had to change it a bit. With this version you still play the same notes just higher/lower for some parts)
