This is (as far as I know) the completely full version of Hawaiian Solo Steel, a very underrated series of stings mainly used in Season 8 of SpongeBob. If there is any more parts, please tell me. This is also the most complete rip on YouTube, and I'd like to thank:
SpongeBob MusiCool
SpongeDivers Music
and TenpenceMusic
for indirectly helping me complete this rip in a cleaner fashion.
All Rights to this music piece (including the audio recording and arrangement) go to Viacom and Nickelodeon, as well as the composers, Nicolas and Jeremy.
