When I saw the trails featuring this year's style, I was intrigued as to how the ident might be... Needless to say it does not disappoint. Lovely animation, really nicely done S4C.
My God, that 1993 ident seems a distant memory now! Incidentally, the soundtrack on that YT clip is not quite that which was used on air.
The essence of it is there; I think the VHS it was digitised from has simply seen better days. I'll see if my old Bottom tape from 1993's recording of "Holy" is still knocking about at my mum's house and upload if I can find it.
