Watching the Detective(Bass guitar)

	        Intro:

|-------------------------------------------------------|
|------7-7-7-7-7----------------------------------------|
|-----------------------5-7--8-8-8-8-8---3-3-3----------|
|--0h5-----------5-5--5-------------------------1-1-1---|

Then, When guitar comes in:

|--------------------------------------------------|
|--------------------------------------------------|
|--------------------------------------------------|
|--5-5--5-3-5---5-5--5--3-0-5---1-1--1-1-1---3-4---|
Repeat

From here on, the bassist improvises. Therefore, you can have fun by improvising as well. 
i only put his because the intro is the coolest bass part in the song anyway. 
(even though there are some cool licks later too)
