The main riff goes:
(The top reads the chords and tags (riffs), the next line is the rhythm figure,
and finally the tabs.  The `>' signifies a slight bend)

(No chords)
   Stella Marie you're my star
   
(The full riff above, then:)

   F#5           A5     B5     F#5         A5      B5
   Stella Marie you're my star

   F#5              A5    B5     F#5       A5      B5
   Stand on ground look up at her

        F#5         A5    B5     F#5       A5      B5
   Just hanging in gold stone

        F#5            A5    B5     F#5    A5      B5
   Just hanging there face froze
  
         F#5          A5   E5
   But I think I see her smiling

   F#5          A5    Ab5
   Think I see her smiling

   F#5          A5   E5
   Think I see her smiling

   F#5          A5   Ab5
   Think I see her smiling

(With riff above:)

   F#5     A5   Tag#1
   Go

   F#5     A5   Tag#1
   Go

   F#5     A5   Tag#1
   Go

   Tag#2
   Go    Go
 

(The second verse, same as the first)
  
   Stella Marie you're my star
   In your blue blue tavern you light my lantern
   O Stella's large
   Pink almond face
   It's glowing in space
   
   A place for heroes only
   Place for heroes only
   Place for heroes only
   Place for heroes only
   Go
   Go
   Go
   Go Go Go Go
   
   Stella Marie you're my star
   I pin you to my chest
   Sell you to the rest
   I kiss her gown
   Send those angels down to woo me now 

   I think I see her smiling
   Think I see her smiling
   Think I see her smiling
   Think I see her smiling
   Go
   Go
   Go
   Go Go
   Go
   Go
   Go
   Go Go
   Go
   Go
   Go
   Go Go


Thar she goes,

Tara now,
Sean
