(over scat singing--"ba ba doo," "doo doo," etc.): 
Sincerely, oh yeah, sincerely 
'Cause I love you so dearly 
Please say you'll be mine 
Sincerely 

(chanting & boisterousness) 
(instrumental) 

(x2): 
Sincerely, don't you know that I love you? 
I'll do anything for you, baby 
All you gotta do is be mine, mine, mine, mine, mine 

Oh love, won't you tell me? 
Won't you tell me? Won't you tell me why I love you? 
'Cause I want you, 'cause I want you, want my sun 
She doesn't want me, want me 
You know she don't want me, want me 
But I'll (never x11) let her go 

Sincerely, don't you know that I love you? 
I'll do anything for you, baby 
All you gotta do is be mine, mine, mine, mine, mine 
All you gotta do is be mine, mine, mine, mine, mine 
All you gotta do is be mine 

(instrumental) 

Sincerely, don't you know that I love you? 
I'll do anything for you, baby 
(repeat & fade): 
All you gotta do is be mine, mine, mine, mine, mine
