Maxi performed with two girl groups and the Irish supergroup The Concerned in the 1970s–80s, also representing Ireland at the 1973 and 1981 Eurovision Song Contests.
[1] When Eamonn Andrews wanted to create a girl group to sing backing vocals for his recording studio, he chose Maxi, Adele King, and Barbara Dixon because of how the combined singing voices sounded; the girls became Maxi, Dick and Twink based on all their respective nicknames.
"[1] At 23 years old, Maxi was chosen to represent the Republic of Ireland at the Eurovision Song Contest 1973, performing "Do I Dream".
When Maxi refused to perform, RTÉ panicked and sent Tina Reynolds to compete in her stead, giving the replacement singer only the flight from Ireland to rehearse the song.
Though she was initially turned down due to her age (28), she eventually joined Marion Fossett and Frances Campbell as the third member of "Ireland's first sexy girl group."
After traveling to Holland and London to record tracks for a new album, the three women of Sheeba were hospitalized at Mayo University Hospital after a traffic collision in Castlebar; Maxi's head injury caused amnesia and needed more than 100 surgical sutures, Fossett received facial injuries, and Campbell had a collapsed lung.
The Concerned also included Dave Fanning, Pat Kenny, Gerry Ryan, Linda Martin, Christy Moore, Mary Black, Adele King, Maura O'Connell, Freddie White, Eamon Carr, Johnny Duhan, Dave King, Clannad, The Blades, Stockton's Wing, The Golden Horde, and Those Nervous Animals.
