I didn't rememer the exact date of Dragonfly or Red Octopus at the time, and will take my answer off the air.
I was bored, and looked it up!
Red Octopus (1975)
Remastered CD, Gold CD and Vinyl issued 1997.
Recorded at Wally Heider's, San Francisco, February, 1975. Released June, 1975. #1 for four weeks.
"Tumblin'" or "There Will Be Love" would've trumped my BOS indeed!
