Meaning of しかも and それで in Yes-No question


I see that しかも and それで usually connect 2 sentence together. But I see them
place at the beginning in Yes-No questions.

1)"しかも歌うんかい"

2)"それで上手いんかい"

Does it mean 1) "(Moreover) is he singing?" and 2) "(So) Is it good?" ?




I would say

１）しかも歌うんかい→（Moreover) Is he singing? (in informal words, I would say 'is he
singing lol') Is correct interpretation.

2) それて上手いんかい→ I would say this interpretation does not suffice. それで上手いんかい
usually follows up after he/she has done something extraordinary before. In
english interpretation, I will say '(after some extraordinary action) and he
is good at it?'

Hope this helps.
