In the song "Be Back Soon," from
Lionel Bart's
musical Oliver!, both
Fagin and his boys (The
Artful Dodger,
Oliver, et. al.)
distinguish the
phrase from "
goodbye."
Cheerio, but be back soon.
I dunno, somehow I'll miss you.
I love you, that's why I
Say "Cheerio," Not goodbye.
The
connotation being the departing
remark is more
familiar than
formal.
Also the name of a week long
calligraphy retreat held in the
Blue Ridge mountains of
North Carolina, where participants get to spend a week with world reknowned calligraphers. Founded in 1984 by Jim and Joyce Teta.
