How many pop groups can you think of that have been influenced by The Mamas and Papas unique sound. There are many vocal groups comprising male/female harmonies that owe more than just a nod to The M's and P's.
I'd love to hear any more suggestions I may have overlooked, as I'm always eager to discover underrated bands from that golden era of pop!
Here's a few to start things off;
FROM the USA
The Fifth Dimension
The Free Design
Spanky and our gang
The Cowsills
The Love Generation
The Peppermint rainbow
The Groop
The Looking glass
Salt water Taffy
The Sunshine Company
Eternity's children
The Collage
From the UK
Brotherhood of man
The New Seekers
Design
Blue Mink
Arrival
Middle of the road
Pickettywitch
The Settlers
From Canada
The Poppy Family
The Bells
The Sugar Shoppe
ABBA from Sweden admitted The M's and P's were an influence in their early days, and their first 2 singles sound remarkably like them, especially He is your brother.
I'd love to hear any more suggestions! Richard.
