Shine On Brightly is the second studio album by the UK band Procol Harum. Released in 1968 after the success of their debut album, it was influential in the development of progressive rock by breaking pop and rock music standards with the 17-minute epic "In Held Twas in I", which marked the beginning of the lengthy progressive rock suites that would occur later in the 1970s. The epic's title is an acrostic, putting the first word of each movement's lyrics into it as shown:
"Glimpses of Nirvana", part 1
"Glimpses of Nirvana", part 2
"′Twas Teatime at the Circus"
"In the Autumn of My Madness"
"Look to Your Soul"
In addition, progressive rock band Transatlantic covered this song on their album SMPT:e. Their version extends "Glimpses of Nirvana" by cutting out "Twas Teatime at the Circus".
The original British and North American versions of the opening two tracks ("Quite Rightly So" and "Shine on Brightly") are different versions.
