Sincere

Gentlemen, gentlemen, what am I hearing?
Say, "Ice cream"
"Ice cream"- but I don't sing young man!
Alright alright, just talk then, just- down here
"Ice cream"
Talk slow
"Ice cream"
You see, singing is only sustained talking
Now you- "Ice cream"
Now you, right here- "Ice cream"
And now you, sir- "Ice cream!"
Ice cream, ice cream, ice cream!
Yeah, oh wow!
Gentlemen, gentlemen-
How can there be any sin in sincere?
Where is the good in goodbye (in goodbye)?
Your apprehensions confuse me, dear
Puzzle and mystify
Mystify, tell me what can be fair in farewell, dear
While one single star shines above?
How can there be any sin in sincere?
Aren't we sincerely in love (oh we're in love)?
