St. Nicholas Abbey RIIP: 222 Song

Since we're on a "Horse" pattern-cluster theme, the following recently recorded on the Deaths in 2014 site stands out:

 St Nicholas Abbey, 6, Irish racehorse.

Note from his wiki page:

St Nicholas Abbey, a bay horse with a white star and stripe and two white feet, was bred in Ireland by Barton Bloodstock & the Villiers Syndicate, a group associated with the Coolmore Stud.

As per the Coolmore stud link:

racehorse trainer, and Robert Sangster

Note from Sangster's wiki page:

Robert Edmund Sangster (23 May 1936 – 7 April 2004) 

As per his birthday:

May 23 -s the 143rd day of the year (144th in leap years) in the Gregorian calendar. There are 222 days remaining until the end of the year. 

Since he was born on a leap year, it was the 144th day with 222 days remaining, an addition to the "Identical Number Sequence" pattern-cluster re the twin 44 and the triple 222, a particular inner twin signature.  Keep in mind that 44 cropped up twice in the previous post.

Note the etymology of Sangster:

This interesting surname of English origin, is either an occupational name for a singer or chorister, or, a nickname for a person who was always singing.
