@ChieftanMews: http://www.youtube.com/watch?v=oX7_C-CLRC8 ; Test 3 ; nth I jot Or
New Tweet tonight from Chieftan Mews containing a Youtube Video link to Flying Over San Jose (BBC2 1975-1976).
Uploaded in 2008 Youtube gives the following description of the file:
This tape was introduced in May 1975 as a new tape and was later twinned with Cheers! to form its later replacement, Five Spanish Dances, which was launched in December 1976. This tape was composed by the Simon Gale Orchestra and included some of the tracks later to be used on Summer Sunny Holiday and Melancholic Rock, and was the first tape to be launched on BBC2 after the decision was made to reduce trade on the channel in favour of a lunchtime closedown in order to save the BBC money and power from January 1975.
According to comments on Youtube Chieftan Mews had previously linked to this video in a Direct Message to a fan six months ago.
Test 3 comes from this being the third TestCard video Mew’s has tweeted over the past two years, the previous ones where on May 15th 2011 ( http://www.youtube.com/watch?v=Ncmg3bxtTB0 and http://www.youtube.com/watch?v=q6SmOBxP9-g ; Test 2 ).
nth I jot Or is a tricky one that appears to have a maths feel.
Nth is a term used for the largest number in a series of ordered numbers.
I is 1 in Roman numerals or may simply be i as an unknown interger.
The Phrase Finder has the following history for the world jot:
A jot is the name of the least letter of an alphabet or the smallest part of a piece of writing. It is the Anglicized version of the Greek iota – the smallest letter of the Greek alphabet, which corresponds to the Roman ‘i’. This, in turn, was derived from the Hebrew word jod, or yodr, which is the the smallest letter of the square Hebrew alphabet. Apart from its specialist typographical meaning, we still use the word jot more generally to mean ‘a tiny amount’. Hence, when we have a brief note to make, we ‘jot it down’.

Or is often used in maths to determine a Boolean operation where one can either be true or false.
It could also be a reference to Or Records a London based independent record label founded in 1998 who specialized in Electronic and Experimental Computer Music including a two edition of their own computer music audio magazine in 1999 featuring Aphex Twin and others.
