Michael Doucet sings this :
(Beausoleil CD « Allons à Lafayette »)
Pauvre 'tit Johnny
Il voudrait danser,
Mais pauvre 'tit Johnny
Il peut pas danser,
Il a essayé
Il a essayé
Mais pauvre 'tit Johnny
Il peut pas danser.
Mais tous les samedis soirs
Mais dans les soirées
Il guettait les jolies filles danser
Mais tu connais il a langui,
Mais pauvre 'tit Johnny
Il peut pas danser
Pauvre 'tit Johnny,
Pauvre 'tit Johnny...
(But you will have to check if you also hear "soirée". I'm not sure of that.
Whose version do you have ?).
My understanding is that this was traditionally an instrumental, until Beausoleil added some words to their version. Since that time, others recordings have words too, such as Wayne Toups rocked up version.
