I did it and posted a video to my Facebook page. I saw a reference in this thread to signing up - I wasn't aware I was supposed to do that.
I am a little embarrassed that the horn slipped a bit in my grip, and my third note (B-flat) had a pitch waver that transcended good vibrato. Nevertheless, I got good feedback from my neighbors.
A few blocks away, a very young trumpet player tried it, and he made a noble attempt - but he started on the 2nd partial (Bb3) rather than the 3rd (F4) and continued from there, one partial too low for each note.
