Stray was an English hard rock band formed in 1966. Vocalist Steve Gadd (born Stephen Gadd, 27 April 1952, Shepherd's Bush, West London), guitarist Del Bromham (born Derek Roy Bromham, 25 November 1951, Acton, West London), bass player Gary Giles (born Gary Stephen Giles, 23 February 1952, North Kensington, West London) and drummer Steve Crutchley (born 1952) formed the band whilst all were attending the Christopher Wren School in London. Richard "Ritchie" Cole (born 10 November 1951, Shepherd's Bush, West London) replaced Crutchley in 1968. They signed to Transatlantic Records in January 1970. 

 

That's the official  Wikipedia entry - the rest of the story, as Paul harvey would say, is that for some ungodly reason this band was lost amongst the shuffle of British greats like Purple, Heep, Zep and the others.  Their debut album is a classic - No filler, all killer - heck Iron Maiden even did a cover of All In Your Mind.

Run Mister Run and the title track Suicide highlight their second album.
