Some European releases (Germany and Spain) had a different B-side: "Round And Round". Portugal, Yugoslavia , Australia and NZ followed the UK choice of B-side with "Why". And Thailand of course put the track out as an EP with three others from non-related artists.
b/w "Round And Round"
A return to epic style with the title track of the new album; probably a stronger single than "Shine On Silver Sun", but it was never going to get very far with the BBC, owing to the obvious drug references.
The B-side "Why" is the first segment of the three-part mini-epic "Why And Wherefore" and, unlike "And Wherefore" as released on the B-side of "Shine On Silver Sun", is identical to that version.
Fairly likely that there was a promo version of this, but I haven't seen one.
"Hero And Heroine"/"Why"
Over in Portugal, non-album track "Why" was the B-side and the sleeve uses the dove image from the album.
The Yugoslavians liked the dove so much they stuck it on the back cover too.
This Australian release is possibly a promo and has a date stamp of 2 Jul 1974. Scans from Alison Brown collection.
New Zealand (AB)
No picture sleeve for the New Zealand release.
"Hero And Heroine"/"Round And Round"
Rather than non-album track "Why", the Spanish release lifted "Round And Round" from the album. The edit begins on the first drum/bass beat of the instrumental section of the song.
German release (*slv)
Very similar to the cover of the Spanish release, with an advert for the Hero And Heroine album on the rear of the sleeve.
Another Thai EP, this time featuring Ozark Mountain Daredevils, Bad Company and ZZ Top as well as the Strawbs. "Heroine" is mis-spelled on both the sleeve and the label.
