All adults stand in a circle with a little space between them. This works particularly well if you have five/six children 3+ who are happy to go around without their own carer. Sing it as many times as necessary. You can lead off, weaving in and out between the other adults, picking up independent children and adding them to the train after each “you will be my master”. When you’ve collected them all, you can then lead the line into the middle of the circle to do something simple, like “Ring-a-ring o’Roses”.

Who will be my master?
Tippy, tippy, tip, tap on my shoulder x3
You will be my master.
Finish by repeating lines 1 and 2.
