For me, the most important thing to take from this weekend is that Andy showed his commitment to play for his country even though he was exhausted. I don't think many other top players would have played a dead rubber, so full credit to Andy for that. Whether or not he sings/doesn't sing GSTQ or Flower of Scotland shouldn't be a big issue imo.
Re the kit, I heard that Andy forgot to bring his shorts to the tie (they had to buy some from Braehead) so maybe he forgot to bring his Team GB shirt too! Whatever the reason, he obviously didn't mind wearing his GB tracksuit so don't think we should read anything into not wearing the GB shirt for his matches.
Couldn't agree more Katie - Andy playing the dead rubber yesterday just shows what commitment he has to his fans, his team and the Davis Cup. I am sure none of the other top 4 players would have played a dead rubber - in fact Rafa said as much - and who could blame them?
I don't see any reason why Andy shouldn't have been piped into FOS - he is Scottish and he was playing in Scotland under a Scottish team captain - it doesn't make him any less British.
Interesting that the Rugby Union authorities have banned the Red Hot Chilli Pipers from playing before the England/Scotland game at the World Cup in New Zealand on the grounds that it might distract/intimidate the Scots' opponents. This from a country that does the Haka before their matches - a war dance that is deliberately designed to intimidate the opposition!
