Whilst they were well produced in comparison to Oneness, I still don't think they were suitable for use into most programming. Larry points out good examples like using 'Festival' or 'Music Video' into music programmes - but these were very much the exception to the rule. Still can't believe they ran with a still of 'Ballet' on the day the Queen Mother died. At least Oneness has, or did have, the sombre 'Forest' ident, and most of the rest of the idents have mostly silent or ambient soundtracks.
Speaking of Rhythm and Movement idents, one of channel4squares1's videos for 24 Hour Quiz during an ASDA advert from 2004, there is a quick glimpse on the TVs playing the end of a BBC One trail then followed a few seconds of the Capoeira ident.
It's about the 13:39 into the video.
