Bluesology, featuring Reg Dwight (Elton John) on piano. Everyday (I Have the Blues) was the B-side to Bluesology's 1966 single "Mr Frantic". "Mr Frantic" was composed and sung by Reg Dwight (who later became Elton John), but this blues classic was sung by Stu Brown, with Reg on piano. The 19-year-old Reg-Elton played a pretty mean blues piano!
