Tabbed by ear - Sounds fine to me.

Capo 2

Single strum through the verse.

Am (x02210@1)  Our love was lost
F (133211@1)                  C (x32010@1)  But now we've found it
                  Am (x02210@1)  Our love was lost
F (133211@1)                  C (x32010@1)  And hope was gone

Am (x02210@1)  Our love was lost
F (133211@1)                  C (x32010@1)  But now we've found it
                           Am (x02210@1)  And if you flash your heart
F (133211@1)            C (x32010@1)  I won't deny it

I promise

Am F C (Strumming)
   I promise

That is basically it. It sounds like a 3 chord bash through most of it to me. 
Try it for yourselves.
If you find anything better feel free to correct me.
