Somewhere I have a list for this kind of thing. Of course I can't find it now 🤔
But well done for specifiying arrival/reflection/departure, I'd never considered it like that. But anyway, off the top of my head and subject to change:
Arrival - Driver, Phish
Reflection - something from Brian Eno & Friends "Apollo", probably An Ending (Ascent) or Deep Blue Day
Departure - Days, probably the Kirsty MacColl version
for those unfamiliar with Phish, here's Driver
"I'll tell you about the driver who lives inside my head
Starts me up and stops me and puts me into bed
He opens up my mouth when it's time for me to talk
Fires up my legs when he wants me to walk
Keeps my eyes open most of the day
Adds to my memory the things that people say
When he makes decisions I don't have to wait
But sometimes it seems he's got to much on his plate
Like this morning when I woke up and he dressed me in this shirt
That looks a little ragged where he dragged me through the dirt
I'm moving through this life and I'm thinking about the next
And hoping when I get there I'll be better dressed"
