What are your opinions of Musicians beside Buglers at Military Internments?

I am a Retiree, U.S. Army (Reserve) and DoD Firefighter, and hold an unusual skill set as a bagpiper. I've done more than a few events for Departed Service Members and Veterans over the years. Often as a member of the VFW Honor Guard. Almost every service I've participated in has had a some variables, mostly due to family requests. But with that said I have a few questions:

What are your opinions of Musicians beside Buglers at Military Internments?
Is there a common tune list, for instrumentals,you feel appropriate?
Do members of the funeral party also understand that climatic conditions can adversely affect both the musician(s) and instrument(s)?
And finally aside from Amazing Grace and Branch of Service Specific Tunes if the musician can play them, what tunes would you like to hear at funeral/memorial services?
