Misc Television - Sealab 2021 Theme chords

Hi.  This is my first tab, so I hope you like it. 
Other tabs on this as well as other sites for this song just 
didn't sound correct to be.  So I did some tweaking, and came 
up with this. Lemme know what you think.

-Nerf22

The Chords used are:
G
B7
C
Em

The Chord order is as follows:
G, C, B7, C, Em, C, G, B7, Em, B7, G, B7, C
[ Tab from: http://www.guitaretab.com/m/misc-television/246287.html ]
The song is played at about 160bpm when played normally, but do it
at your own speed.  On an electric with slight distortion makes the 
song sound pretty authentic.  Even tweak to play an acoustic version,
whatever floats your boat.

If you're lookin` for me

                             B7 (PM, 8th notes)
You'd better check under the sea

              Em     C
Underneath at Seeeea Laaaab

Underneath the water

Seeeea Laaaab

At the bot tom of the sea

There you have it.  Hope you like it.
