illustrates the tradeoff between audio quality and degree of compression.
It has the first part of the song at high quality, followed by the first
chorus at three different quality levels:
- Through first chorus at original quality, 0:00–1:40
- Repeat of start of first chorus at FM radio quality MP3, 1:45–2:00
- Repeat of start of first chorus at AM radio quality MP3, 2:05–2:20
- Repeat of start of first chorus at poor quality MP3, 2:25–2:40

The New Liberty Jazz Band,
from their CD Two to Two.
From the allbum cover:
“This tender love ballad by Friedman and Whitson was transformed from a
waltz to hot jazz by the New Orleans Halfway House Orchestra in 1925. We
follow in their path, adding a trombone solo by Jay that, if it conjures up
a vision of Tommy Dorsey playing at the Totem Pole Ballroom, is probably due
to indigestion. The band is especially proud of the cornet-saxophone duet
noodle by Bobby and Bruce accompanied by Dan’s and Roland’s banjos.”
