Maybe Genesis' 'Vancouver'? It has a synth line in the verses that is similar.
When I posted this, I kept thinking it must be a Genesis song or something from that camp because it sounded so familiar — which is why I shared it here.
But then this morning it occurred to me, it sounds like the melody of the chorus from "The Circle Game," one of my favourite songs by Joni Mitchell.
"And the seasons, they go round and round
And the painted ponies go up and down"
I don't know how many Joni Mitchell fans we have here but probably not so many that I would have been bombarded with the answer I was seeking.
