According to Palestine Press Agency, this was the first time that a US president heard the Palestinian National anthem - and the first time a president bowed to the flag of "Palestine."
If so, this would appear to be a breach of presidential protocol. Presidents aren't supposed to bow, period.
Ma'an also reports that the band that greeted Obama botched the US National Anthem.
Waiting to find the video....
UPDATE: Don't see any bowing in this video. The band plays very poorly but I'm not sure I would say "botched."
