The First Progressive Epic Song

Transatlantic - In Held 'Twas In I (Roine Stolt Mixes)

<In Held 'Twas in I> is the first progressive epic song released by Procol Harum in 1968 and an acrostic: 
"In the darkness of the night..." 
"Held close by that which some despise..." 
"'Twas tea-time at the circus..." 
"In the autumn of my madness..." 
"I know if I'd been wiser..."

The title of the song is so remarkable as well.

This version is mixed by Roine Stolz, a member of Transatlantic.
