Instead of simply starting the melody:

Intro

In C:

| Cmaj7 | A7 | Dm7 G7 | C |

Then begin melody.

During long/resting melody points:

use tiny fills.

At the final phrase:

repeat it once.

Then end:

F → Fm6 → C6/9

You have transformed a children's melody into an arrangement without changing its identity.
