Your english is just fine, frarosano, and you don't have to apologise for being Italian. It's ok.
verse: D A Em G (x4)
bridge: Bm G A D
chorus: G A D
(D)Outside there's a (A)box car waiting
(Em)Outside the (G)family stew
[BRIDGE]
(Bm)There is a wait so (G)long (so long, so (A)long)
You never wait soooo (D)looong
[CHORUS]
(G)............(A)Here comes your (D)man
(LAST BRIDGE) (C chord not G)
(Bm)There is a wait so (C)long (so long, so (A)long)
end on D
The chords were in the wrong place if you reading from the tablature instead of playing to the song.
Use open chords for verse and barre chords for chorus
Hope this helps, a little.
