The Carpenters (1976) Calling Occupants Of Interplanetary Craft‏

Starting with a mock transmission of some aliens contacting a corny radio DJ during a call in before Karen Carpenter's delicate voice enters on a cloud of soothing electric piano. Her angelic vocals are on form and the introduction of horns and distorted guitar solo actually work as the song builds to giddying heights; this was a genuine message to visiting extra terrestrial beings.  Despite the pastoral flute and strings and the inclusion of the pitched alien voice it is still an interesting if dated pop gem. It's an interesting notion as there is no more better artist to provide a non- threatening welcome to outer space than The Carpenter's friendly and warm arrangements.
