I found out about this about 2 years ago at my uncles funeral (Vietnam Vet, welcome home sir).
He had to option to be buried at the Houston National Cemetery (where he would have had a live bugler), but chose to be buried at a local cemetery instead. No live bugler was available, so they used one of these, and I did not know till I talked to the bugler afterwards when I went to thank him. He was a little embarrassed to tell me, but as said above, I think it is better to have the symbolic player vs just a recording playing over a speaker.
Brought tears to my eyes for sure, recording or not.
And a totally separate topic, what is wrong with that reporters face on the 2nd video, looks like somebody punched her in the face.
Why do people think that looks good?
