First recorded by “Mama” Cass Elliot (1969).
Hit version by Bobby Sherman (US #9/MOR #2/CAN #9 1970).
From the wiki: “‘Easy Come, Easy Go’ was first recorded in 1969 by ‘Mama’ Cass Elliot for her second solo album, Bubble Gum, Lemonade & … Something For Mama. A year later, teen idol Bobby Sherman recorded a cover version that charted Top 10 in the US and Canada. The Cass Elliot album was recorded in the wake of her breakdown following a disastrous Las Vegas show in 1968. Studio executives at Dunhill Records took creative control the fastest and easiest solution would be to have Elliot record an album full of music similar to what she had done with The Mamas & the Papas. The album was originally released on July 5, 1969 with 11 tracks and was a moderate success when first released, reaching #91 on the Billboard Hot Album chart. But, the album was re-released in December 1969 under a new title and with a different album cover as Make Your Own Kind of Music/It’s Getting Better. ‘Make Your Own Kind of Music‘, which had been recorded separately from the album sessions, had become a hit and was belatedly added to the album.”
