Mac help

My mac has a built in microphone. I thought I'd record myself singing and post it for fun. But, like an idiot, I deleted Garage Band (I wanted to know if I could get rid of applications that came with the computer). I thought it was a game and surely I'd never use it. Adam now tells me it's the basic recording application. I went to the Mac site and tried to down load it, but my computer tells me it can't find the appropriate application.

Can anyone help me get it back? I already emptied the trash a few days ago, so it's not recoverable from there.

Silly me.

Australia is on fire

Oh god, the news is awful. The heat there just hasn't died down and Victoria is ablaze. It's horrifying. Oh my Aussie friends, I hope you stay safe and cool!
