ZZ Top singer-guitarist Billy Gibbons was back on stage Saturday night in New York -- but bandmates Dusty Hill and Frank Beard were only in the audience.

Gibbons reunited his pre-ZZ band, The Moving Sidewalks, for its first performance in 44 years, at B.B. King's. The show was in support of a recently released compilation of the little-known psychedelic combo.

Gibbons formed The Moving Sidewalks in Houston in the mid-'60s. The band opened for Jimi Hendrix, The Doors, Ten Years After and many others. The band, which released its only album, Flash, in 1968, dissolved the following year when two of its members were drafted.

Speaking at rehearsals on Friday in New York to Premiere, Gibbons said, "It's been quite an entertainingly and unanticipated delight to regather The Moving Sidewalks. Getting back together to do these things is a time travel -- instantaneously." The band has another show scheduled for April 28th in Austin, Texas. Gibbons says there is a chance they may do more, and perhaps get in the studio for new recordings.
