Outback Steakhouse Drink Recipe Wanted

I am looking for a recipe for an “Old Fashioned Ruth”.
Outback company owned restaurants used to have it on their menu and in their drink recipe book. I lost my copy of the recipe and would love to have it again.
Some of the ingredients are… crushed strawberries, sprite, coconut rum.

A Google search turned this up (have not tried it):

"…Old Fashioned Ruth from Outback

splash of Sprite
juice from 1 lemon slice

bottom of the glass with a splash of Sprite.

add the juice from 1 lemon slice at it’s like fruit salad in a glass…"
