am trying to find episodes of two different shows, based on moments alone. the google is not helping!

-the episode of Stargate: SG1 where Jack and Daniel have the little rolly ball game - possibly on a teltak/in the midst of imminent peril/in a place that looks kind of Goa'uldy?

-the episode of the Granada Sherlock Holmes where Holmes has a musicgasm at a concert while Watson gazes on adoringly

these ringing any bells?
