Place maraschino cherry in center of each peach half; place cut side down on the brown sugar (cherries will be on the bottom).
Spoon pineapple around peaches.
Add enough water to reserved pineapple juice to measure 1 1/4 cups (I used pineapple juice and fruit juice out of the peach cans!).
In a large bowl, beat cake mix, juice mixture, oil and eggs with electric mixer on low speed 30 seconds. Beat on med speed 2 minutes, scraping bowl occasionally. Pour batter over peaches and pineapple.
Bake 1 hour or until toothpick inserted in center of cake comes out clean and top is VERY DARK GOLDEN BROWN.
Immediately run knife around side of pan to loosen cake. Place heatproof serving plate upside down on pan; turn pan and plate over. Leave pan over cake 1 minute so topping can drizzle over cake.
