Good idea to name the keynote speaker of a local conference at which my paper was accepted to be presented? I am applying to doctoral programs in the US, and I am wondering:

Is it advisable to name the keynote speaker of the local conference where I presented a paper recently?

The keynote speaker is a well-respected expert in my field, and I thought of mentioning his participation in order to highlight the merit of this conference in my statement of purpose.
It seems to me that only a conference with a certain level of importance would be able to get such a reputable expert as a keynote speaker.
If the conference is well-known enough, then it isn't necessary to name the keynote speaker, because the conference will be recognized regardless. If the conference isn't well-known in the field, name-dropping is going to come across crass and not very helpful.

So in either case, I don't see any advantage to name-dropping.
