Summer Lightning    Ralph McTell

(Em*) (Gj7/D) (Cj7) (C) (G)
(Em*)Move (Gj7/D)over (Cj7)here,
Come (C°)on, sit down be(Bm7)side me,(bass run G-F#-E to)(Em)
Oh, (Am7) closer now, (D) come and (G5)put (G5/A)your (G5/B)arms,
(G5)Put (G5/A)your (G5/B)arms a(Cj7)round me.
Oh, you (C°)had a bad day, (Bm7)too,
(Bm7/G)And (Bm7/F#))I (Em)feel the same as (Am7)you, (D)
Come on, sit (G)down. (Cadd9) (G)(hold)

It's just that when (Am)I get (Am/G#)mad,
I end up (Am/G)saying things
If I (G5)thought about, I (Bm)wouldn't ever (Em)say.
And I (G5)think that you (Am7)already (G5)know that,
But I'll (Fadd9)say it, anyway,
(Cadd9) Oh, I'll (Cj7)say it, any(G5)way. (Am7) (G5)
(Em*) (Gj7/D) (Cj7) (C°) (Bm7) (Bm7/G)(Bm7/F#)(Em)
(Am7) (D) (G) (Cadd9) (G)(hold)

It's just that when (Am)I get (Am/G#)mad,
I end up (Am/G)saying things
If I (G5)thought about, I (Bm)wouldn't ever (Em)say.
And I (G5)think that you (Am7)already (G5)know that,
But I'll (Fadd9)say it, anyway,
(Cadd9) Oh, I'll (Cj7)say it, any(G5)way. (Am7) (G5)

(Em*)Don't (Gj7/D)let the (Cj7)day go (C°)down,
The (Bm7)two of us still fighting,(bass run G-F#-E to)(Em)
It's (Am7)not a storm at (D)all,
No, it's (G5)on(G5/A)ly (G5/B)Sum(G5)mer,
On(G5/A)ly (G5/B)Summer (Cj7)Lightning,
And (C°)we've still got the (Bm7)night
(Bm7/G)So (Bm7/F#)there's (Em)time to put it (Am7)right, (D)
Let's go to (G5)bed. (Cadd9) (G)
