Question: Are Emily Whitehurst and Dave Cousins both American singers and songwriters?
Context: "Hey Little Man ... Thursday's Child" is a song by English band Strawbs written by Dave Cousins.  The track is to be found on the "Grave New World" album and the lyrics depict a father talking to his son.  The song can be considered to be continued on a later track from the same album – "Hey Little Man ... Wednesday's Child", which has the same tune but different lyrics.  The song is performed solely by Dave Cousins. Hummingbird is a studio album by Rick Wakeman and Dave Cousins.  The songs are a mixture of jointly-composed originals, reworkings of songs from Strawbs albums and Dave Cousins' solo album "Two Weeks Last Summer", together with Wakeman instrumental compositions presented as codas to the Cousins songs. Grave New World is a studio album by English band Strawbs.  It was the first album to be released after the departure of Rick Wakeman, under circumstances about which band leader Dave Cousins was very bitter.  Cousins has admitted that the track "Tomorrow" was written about Wakeman.  Happily their friendship survived and the two have since performed and recorded together, releasing an album "Hummingbird" in 2002.

They were founded by Dominic Davi who left in 2003 and underwent numerous lineup changes, containing almost no original members by the time of their disbandment in 2005.

This vinyl LP has been in the UK's top 10 of collectable vinyl, being listed in Millers Antique Collectable guide.  A 2008 archival release, The Magic Shoemaker Live, features live recordings of the original Fire line up, plus Paul Brett and Dave Cousins (Strawbs), with Ray Hammond as the narrator.

Cousins damaged his wrist and Dave Lambert stepped in to cover while Cousins sang.  The format was successful and tours were arranged.  Brian Willoughby stepped down in 2004 to concentrate on his work with Cathryn Craig and he was replaced by Chas Cronk who added bass pedals and acoustic bass guitar as well as extra vocals and guitar.

In 1998, she began her music career by fronting the punk rock band Tsunami Bomb.  After Tsunami Bomb disbanded in 2005, she co-founded and fronted the Action Design; a rock group.  Since 2012, Whitehurst has been working on her synth-driven, indie pop project, Survival Guide. The Action Design is an American rock band formed in Petaluma, California, after the breakup of the former punk rock band Tsunami Bomb.  Emily Whitehurst and Matt McKenzie came together to produce a new band, self-described as "a refreshing mix of the band's punk rock roots infused with hard hitting dance rhythms and catchy basslines wrought with think memorable vocal hooks".  In January 2011, on their official Facebook page, the band announced its members are currently focusing on other musical projects rather than The Action Design.
