This page is meant as a study for how to play this song and is not my original work. 

sealab theme by calamine

G                           C

     if you're lookin' for me

                             B7

you'd better check under the sea

                            C

'cause that is where you'll find me

              Em      C

underneath at seeeea laaab

G              B7

underneath the water

Em     C

seeea laaab

 G            B7           C

at the bottom of the sea

This song has been re-tabbed by Cameron Fulford and I think you'll all find that it sounds much better if you play it this way.  Here is how to play the chords*:

B7      C      G    Em

---    ---    ---   ---

e 2    e 0    e 3   e 0
b x    b 3    b 0   b 0
g 2    g 0    g 0   g 0
d 1    d 2    d 0   d 2
a 2    a 3    a 2   a 2
E x    E 0    E 3   E 0
 

*there are a few different ways to play C, G, and Em, these are just the easiest for me.
