  • Handsome old chaps 🤣

    I already reviewed SN audio and it beggars belief that Apple cannot link the two versions. Anyway, I enjoy watching SN in video format (my wife less so) and the two old crooners do a great job in keeping me updated. I‘ve been listening for longer than some people have been alive, certainly from before Leo got his longest crowdsurfing award at some DiggNation event…!! Live long and prosper!
