Since 2008, he has been based in Japan, where he has played a key role in the development of Toyota Verblitz and latterly Coca Cola West Red Sparks.
On his move to Glasgow, Angus said: ďIím really happy to have signed for Glasgow Warriors and Iím excited by the opportunity of playing for a club where thereís a concerted effort to achieve success.
ďSince this move became a possibility, Iíve been keeping a close eye on how the team have been performing in the RaboDirect PRO12, and itís clear theyíve got a tremendous spirit and sense of purpose in what they do.
ďTheyíve got every chance of making the play-offs and theyíve recruited and retained a good number of players, so itís a positive environment to be coming into.
ďThe aim will be to use everything Iíve learned in the southern hemisphere to bring my own influence to the table. My overriding feeling right now is one of real anticipation. Itís a great new challenge for me, and one I canít wait to get stuck into.Ē
