8-Track Flashback was a TV series hosted by David Cassidy, Leif Garrett and Suzanne Somers. This rhyming title refers to the fact that it is a "flashback" to the popularity of 8-tracks in the 1970s.
A select few 8-track tapes, including a rarity from Frank Sinatra and some '80s classics, have sold for hundreds or even thousands of dollars to collectors.
