Enoch Kent recorded 'We're only over here for exploration' with his group The Exiles on their album 'Freedom, Come All Ye' Topic LP 12T143. I don't know whether it has been reissued on CD. I have a cassette of it somewhere in a huge bin of jumbled cassette tapes gathered over decades so I wouldn't hold out much hope of finding it in a hurry. I will have look though. At least, this will bring your request back to the top, and someone may have the album.
