The title of the epic "In Held 'Twas in I" is an acrostic. It is formed by taking the first word of the lyrics in each of the first four movements (the 2nd word "held" comes from the first word of the sixth verse in the first movement).
"In the darkness of the night..."
from movement 1 "Glimpses of Nirvana"
"Held close by that which some despise..."
from the sixth verse of movement 1 "Glimpses of Nirvana"
Shine On Brightly was released in September 1968 by record labels Regal Zonophone and A&M. The original British and North American versions of the opening two tracks ("Quite Rightly So" and "Shine On Brightly") are different versions.
The album was reissued several times, including a 2009 remaster using the original 2-track stereo masters and featuring bonus B-sides and alternate takes. However, many of the tracks are played at a higher speed. Subsequent reissues have been at the correct speed.
Upon its release, Jim Miller, writing for Rolling Stone, was unfavourable: "Procol Harum's first release was generally more satisfying, especially since this new album displays little in the way of startling growth – the group has apparently chosen to refine their old approach and the musical result, while usually listenable, is not consistently interesting."
