First single release by B.W. Stevenson (US #66/SA #8 1973).
Other hit version by Three Dog Night (US #3/CAN #4/SA #13 1973).
From the wiki: “‘Shambala’ was written by Daniel Moore and made famous by two almost-simultaneous releases in 1973: the lesser-known but first-released version by Moore’s sometime-collaborator, Texas singer-songwriter B.W. Stevenson (‘My Maria’), and the better-known but slightly later-released version by Three Dog Night. While the Three Dog Night arrangement was the first to be recorded, in December 1972, it was released on May 19, 1973, one-week after Stevenson’s February 1973 recording.
