The late Don Ho was a guest on "The Glen Campbell Goodtime Hour" in 1969 where he introduced "Galveston" (Webb) to the host. Don had already released the tune as a B side in 1968. There is a slight difference in the lyrics between versions.
The composer Jimmy Webb's version is next. You'll find it on the 1972 album "Letters" and other Jimmy Webb releases.
FYI, here are clips of the German and Swedish covers.
Glen Campbell won four Grammys in 1967 alone. In 1969 his cover of "Galveston" topped the charts and is from the album of the same name. The song is considered the official anthem of the city and the island in Texas.
