Anyone who knows Ringo Starr's music well? I'm looking for a song name...?

This morning I heard a song on the radio by Ringo and I can’t find the name of it anywhere. There wasn't any one else singing with him, not a lot of background drums, mostly piano. The only part of the lyrics I remember is from the beginning, he says something about someone being "on my mind" or "in my mind" and it's about missing someone or not seeing them anymore? I've checked all the local radio stations playlists and none of them go back to 11 am. I know it's not too descriptive but if anyone had any suggestions as to which song it is, I would appreciate it!
