happy days theme alt. 2 season unreleased HD

This version of happy days song is different from opening song,it was recorded by Jim Haas with a group of other session singers for the first two seasons (Jimmy Haas on lead vocals, Ron Hicklin of the Ron Hicklin Singers, Stan Farber, Jerry Whitman, and Gary Garrett on backing vocals, and studio musicians.- the "original cast")and you can hear this version in the final scenes of the episodes of the second season. I have assembled the various parts, reconstructed it in full. The vocal performance is good, the text is different in the chorus, but there are already the first verse and the third .At the end, I added a different ending,( "these day is our...these are such happy days ") present at the end of some episodes before the final theme song.
