What's the meaning of "guest spot" in "We have a guest spot on the Tonight Show"? [closed]

I think that "solo spot" has the same meaning, but I don't know the meaning either.

If you check with CED you would realize

spot

a position or length of time in a show assigned to a specific performer

In the parlance of television production, a "spot" is simply an appearance role. An actor may say something like "I got a spot in a commercial". They have a role appearing in a commercial.

Aa guest spot is an appearance role for a guest. A guest is someone who is not part of the regular cast.

I have never heard "guest spot" refer to a guest crew member (someone who does not have an appearing role). However, the Tonight Show is a little different from most television productions. Some crew members will frequently have appearance roles while they are doing their regular job (like announcing or operating a camera).

A solo spot follows from this. It simply means appearing alone on screen.
