I rarely watch TV, but here's one I can contribute by a link. Since centuries (or decades?) of old, the children program in German TV ends with the 5 minutes appearance of Sandmännchen (the little sandman; John of dreams).The lyrics printed in the score (Sandmann, lieber Sandmann, es ist noch nicht so weit) start the five minutes, and the lyrics (not immediately) below that (Kinder, liebe Kinder, es hat mir Spass gemacht...) are the goodbye song.
