A Most Happy Fella...

 Cover of the original cast album

done in 1956...called by Stanley Greene,

"one of the most ambitiously operatic works ever written 

for the Broadway theatre..."

 Goodspeed Opera's production...

the opening number...The Most Happy Fella!

 ...and "Standing on the Corner..."

 The original Rosabella and Tony,

Jo Sullivan and Robert Weede.

Hopefully Jo is standing on a box for this!

 The original production was partially bank-rolled

by Lucy and Desi Arnez...

and was featured in an "I Love Lucy" episode:

"Lucy's Night in Town."

Fred Mertz comments re the title of the show,

"The guy is not married."

Frank Loesser (book, music AND lyrics for this show)

and his first wife, Lynn Garland,

who helped produce and cast.

Unfortunately, she "cast" herself out of this marriage,

when Jo Sullivan (Rosabella) caught Frank's eye.
