on the most recent advert, what it the song? its the same song played on the pixar short knick knack? the bupa adverts with the triangle, circle, square, and other colourful shapes jumping about the pace, the triangle listening to its ipod.
having looked extensively finaly found that it is called --hold your breath---knick knack!!! and can be found on the Bobby McFerrin website ( www.bobbymcferrin.com) under 'The Bobby-Shop. Put your cursor over the circles at top of screen and it will be found on the far right. Hope this helps!!
