Great song... songwriter John Phillips, per claims by his daughter(s), was a degenerate perv of the highest order, but, yeah, helluva song.
John Phillips was a great vocal arranger and certainly the equal of Brian Wilson in that era.
I saw an interview of Michelle Phillips who said she hated “Monday, Monday” - it was so simple. But after a few years, she came to love it as one her favorites in large part to the vocal arrangements.
“California Dreamin’” was a catalyst for me to move to Hollywood and transfer from Cincinnati to UCLA in June,68...just as Manson was recruiting his family.
Michelle Phillips contributed one line to the song, ‘I got down on my knees and I pretend to pray’. She got co-writing credit, and earned half the royalties, which have amounted to a fortune. She’s talked about how lucky she was when she was asked to help with the song.
