Observations one at a time is this a valid illustration?

Is it possible to illustrate the collapse that occurs when one measures in detail a photon going through the beam splitter and at the same time loses the diffraction pattern to be the same as studying players in an orchestra. While a full orchestra is playing if you decide study one player and isolate just the music the individual plays you create a situation whereby you cannot hear the music the whole orchestra is playing. It would be nice to be able to at anyone moment receive data from both the orchestra and the player but this is not possible. You can either hear the whole orchestra (the diffraction pattern) or the sound produced by one player ( analyze specific data related to one photons movements).

 

[Bandersnatch]

The analogy doesn't work, since you can have one musician that sounds like an orchestra when you're not paying attention, or like a single guy playing - when you are.
