At least i think its the Yetties, all I can remember of the lyrics are

With his traps and guns and snares he will seek out foxes lairs
and the warrenwhere the rabbits often lurk
with his pair of trusty hounds who'se devotion knows no bounds
Yes its all part of the game keepers work.

I know nothing all about this song other than it was on an old tape of Yetties songs about 25years ago and those lines have always stuck in my mind
