Consider Yourself Lionel Bart, from Oliver!

Consider yourself at home
Consider yourself one of the family
We’ve taken to you so strong
It’s clear we’re going to get along
Consider yourself well in
Consider yourself part of the furniture
There isn’t a lot to spare
Who cares, whatever we’ve got we share
If it should chance to be we should see some harder days
Empty larder days, why grouse
Always a chance to meet somebody to foot the bill
Then the drinks are on the house
Consider yourself our mate
We don’t want to have no fuss
For after some consideration we can state
Consider yourself one of us!
