Is this it then?

Beware of the bite of the underdog,
his teeth are rotten, but more dangerous for that
Beware of the bite of the underdog
If he gets loose you better hold on to your hat
Too late then to calm him or placate him
Or to feed him when already he's fed up!
For life my friend can be very capricious
and they think that that's it?

Can you send me the song then Breezy so we can practice it on Friday :-)
