2. Hawaii Five-O - 'Theme Song'
The instrumental theme to Hawaii Five-O is another theme song that was so incredibly popular that it charted all across the country. The Ventures version of the song reached Number 11 on the Billboard Hot 100 in 1969, and it has since become a standard for marching bands. The new version of the show originally updated the song with synths, but after a huge negative reaction they quickly returned to the original sound – albeit at half the length. The days of a one-minute theme song are long over.
