Yes! Good solve!

8. chorale (hidden word)

Well spotted!

4. Sailing canoe by myself across part of the Pacific (7)

Sailing = anagram ind.
canoe = Ocean
myself = i
across = a
part of the Pacific = Oceania (direct)

Good job, Koala!

Hints added!

7: Part of a flight heading to Rome is evacuated earlier (5)
Riser = part of flight (of stairs!).
R(ome) IS E(arlie)R ; if so, "evacuated earlier" is really neat!!

Good solve, Denis. I liked that one, too.

The last one is a simple charade. The clue splits where you don't expect it to.

2. Be overly frugal and fail to report income partner's capital (5)
cheap?
cheat = fail to report income
p = partner's capital (capital letter = first letter)
...probably wrong; don't see anything indicating "t"
being replaced by "p"...

2. Be overly frugal and fail to report income partner's capital (5)

skimp - be overly frugal

skim - fail to report income
P(artner's) capital


meant to replace the above with this

Well Sondi, "cheap" is probably wrong:
changed my mind to SKIMp(artner's capital) !

You nailed it, Sondi!
