This is the only video I've found of MayTree from 2007. It was recorded live at the Motongi Cafe. (I'm not 100% sure of that name in English, since the place closed in 2015 and details are scarce; "모통이" translates to "cornerstone", so maybe an alternate reading would be "Cornerstone Cafe"?).
These are the earliest renditions of "Sunset Glow" and "Turn the Beat Around" that I've found. I'd always assumed that MayTree added "Sunset Glow" to their repertoire due to Big Bang's cover version being a huge hit in 2008, but this video proves me wrong. MayTree's version must be based off of the 1988 original by Moon Sae Lee, since it precedes Big Bang's version by about a year.
MayTree at this time was six members:
Sang-In "S.I." Jang 장상인 (vocal percussion/founder) 2000 - present
Sookyung "Soo" Kang 강수경 (alto/music director) 2000 - present
Hongseok Choi 최홍석 (bass) 2000 - September 2013
Kyungyoung Choi 최경영 (tenor) 2001 - 2009
Yeonju Han 한연주 (soprano) 2006 - 2009
Dohyun Yoon 윤도현 (high tenor) 2007 - 2010
