— a new bonus reel from Audiotape 

Some of our greatest popular songs — hits like "Full 
Moon and Empty Arms," "Till the End of Time," 
"Stranger in Paradise"— took their melodies from the 
classics. Eight of these lovely themes— in their original 
classical setting — are the basis for "Classics that Made 
the Hit Parade," a program with strength, variety, and, 
of course, rich melodic beauty. 

This unusual program, professionally recorded in 
sparkling full fidelity on Audiotape, is available Right 
Now from Audiotape dealers everywhere. (And only 
from Audiotape dealers.) Ask to hear a portion of the 
program, if you like. Then, take your choice of a half- 
hour of two-track stereo, or 55 minutes of four-track 
stereo or dual-track monaural sound — all at 7% ips. 
Don't pass up this unique opportunity. 

"Classics that Made the 
Hit Parade" makes an ideal 
addition to Audio's first two 
bonus reels, "Blood-and- 
Thunder Classics" and "High 
Spirits," still available at 
Audiotape dealers.
