happy days theme song original complete

THis is a NEW reconstruction of the opening song of third and following seasons of "happy days"
, full of FOUR verses, . I used the first verse released in the 45 rpm record, while the second , the third verse only found in the score ( background music ) of the first episodes of season one
( the middle assolo is a mix between the assolo in season-theme from the third to the tenth , and the solo sax appeared in 11th season.) .The original song was first recorded in 1974 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")These versions of the song were used ONLY for the ending credits of Seasons 1 and 2, ( because an updated version of "Rock Around the Clock" by Bill Haley and His Comets was used as the opening theme). The song was re-recorded in 1975 by Jim Haas with different lyrics for both the opening and closing credits for Seasons 3 through 10 ....Pratt & McClain released the song - complete of all verses - as a single in 1976 from their album Pratt & McClain Featuring Happy Days. The complete original song was never released by the original cast.
this is why I made this reconstruction.
at the end there is a small surprise, the ending choir with a different words: "these are such happy days" , wich can be heard at the end of the first episodes in season 1.LYRICS:
