Also, in late 1969, another British band (Jethro Tull) recorded Ian Anderson's "For Michael Collins, Jeffrey and Me.""Out of my Book" by Peter Hammill (Van Der Graff Generator) ? That was recorded on that band's 2nd album in late 1969.
The verses could have a slow Brasilian beat (which is already kinda implied, if you ask me, based on the acoustic guitar figure) -- and the chorus/refrain could have a double-time (double-tempo) Brazilian-type beat, as well.
It could have a similar style/"feel" to "Sometimes in Winter" (on Stillness).
Also, from Tull's 3rd LP -- Benefit -- is another song "Inside" which is a possibility for a treatment -- or, at least, for an early 1970s Lani solo recording, maybe? (I had previously mentioned "Alive and Well and Living In" -- which was originally on the U.K. but not U.S. version of that album. That song finally saw American release on the Living in the Past compilation in 1972.)
