This group of Daybreakers were from Iowa City, Iowa. Their song "Psychedelic Siren" is now regarded as a classic, it's not hard to hear why! However, I don't quite find that siren to be pyschedelic tho'...heh heh!!
The band reformed in the '70s and were known as Cruisin'. The singer, Max Allan Collins, went on to become a mystery novelist; his Road to Perdition was made into a Hollywood film in 2002!! The Iowa Daybreakers had no connections to the Ohio (Billy Dawn and) Daybreakers, that groups seems to have only recorded a demo, never made any records.
