[2] An animated music video, featuring drawings by regular Super Furries sleeve designer Pete Fowler, was produced to accompany the release of "Hello Sunshine" as a single.

The band turned down "a seven-figure offer" from Coca-Cola to allow the use of "Hello Sunshine" in an advertising campaign citing alleged malpractice on the part of the drinks firm.

The last syllable of the line "...so hard to say goodbye" is held and pans from left to right until "Hello Sunshine" itself begins with Gruff Rhys singing the title phrase, joined by the band on the second word.

The first chorus enters at 1 minute 13 seconds with Rhys being joined by falsetto harmony backing vocals on the lines "In honesty it's been a while, since we had reason left to smile".

[11] The song breaks down for the bridge with just arpeggio guitar, simple bass and occasional drum rolls playing as the lines "Hello sunshine, come into my life" are sung.

The outro follows during which the title phrase is sung five times before a lead guitar line heralds the end of the song with Rhys singing "Come into my life".

The first, by Weevil, is 4 minutes 22 seconds in length and is largely based around samples of lead guitar from the track along with occasional snippets of Rhys's vocal.

The track ends with a brief clip of the band's road manager, in the guise of 'Kurt Stern', giving a fictionalised account of Phantom Power's production.

[16] The 'summery' nature of the track was commented on by several journalists with The Observer calling "Hello Sunshine" a "gloriously hazy opener" and Music Critic describing it as "passionately mellow summer doo-wop".

[17][18] However BBC Wales, although describing the track as "an excellent song and a near perfect album opener", called the decision to release "Hello Sunshine" as a single "rather mystifying" stating that it is "a world away from the SFA we've grown to love over the years".

The picture of the horse on the box flies away as he looks at it and lands on one of five hot air balloons flown by cartoon representations of the Super Furry Animals.
