The Equals only had one hit in the US, as they were much more successful in the UK and elsewhere. As it was, "Baby Come Back", released in 1968, only went as far as #32 on the Hot 100 here, but hit #1 in England.
The group's only other claim to fame is guitarist-vocalist Eddy Grant, who left the group a few years later and began a solo career that saw him return to the American charts in 1982 with "Electric Avenue". However, Grant is not the lead singer here. Derv Gordon has those chores.
