Please - need help with parsing.
15 dn - As one appears in lounges, often {9].
Answer must be REGULARLY but why ?
20 dn - See a musical's MC {5}.
Answer must be CHAIR but why ?

c hair?

[dannyk13]

Chair - c(sounds like see) + hair(musical)

[Bricklayer]

Thanks for that - Ideas on 15 dn ?

[aelmpvw]

as = eg
one = a
