"Will You Be Staying After Sunday" by The Peppermint Rainbow

You can't get anymore groovy than The Peppermint Rainbow, a band fronted by two sisters out of Baltimore, Maryland. They scored two charting hits in 1969, "Will You Be Staying After Sunday" and "Don't Wake Me Up In The Morning, Michael," which reached #32 and #54, respectively. That is where the pot of gold ended. Subsequent singles couldn't get any traction, and the group quickly broke up.
