Limited double vinyl LP pressing package contains both mono and stereo versions of the album. Butterfly is the second studio album released by The Hollies in 1967, their seventh in England overall. It was also the last new Hollies album to feature Graham Nash until 1983's What Goes Around. This, like it's predecessors For Certain Because and Evolution, featured songs written solely by Allan Clarke, Graham Nash, and Tony Hicks. This album was really a Graham Nash-led project, and he featured as lead vocal more than on any prior album. As with Evolution, none of the songs on the album were selected for single or EP release in the UK. In the US, "Dear Eloise" was issued as a single A-side while "Try It" and "Elevated Observations?" were issued as B-sides of the "Jennifer Eccles" and "Do The Best You Can" singles, respectively.
