As a girl my parents had tape which I thought was Lawrence Welk and included song called Go away little Tie Yellow Ribbon round. What album it who with the welk?

The song "Tie a Yellow Ribbon Round the Ole Oak Tree" was not actually recorded by Lawrence Welk. It was originally recorded by Dawn featuring Tony Orlando in 1973 and became a crossover hit, topping both the pop and country charts in the US. However, it is possible that Lawrence Welk may have performed a cover version of the song on one of his television shows.
