Ten Man Mop or Mr. Reservoir Butler Rides Again is the third album by Steeleye Span, recorded in September 1971.

Tracks like "Four Nights Drunk", "Marrowbones", and "Wee Weaver" are essentially pure folk.

The even more curious subtitle is a reference to Reservoir Butler, who had originally performed one of the songs covered on the album.

When Castle Music re-released Ten Man Mop... it added a substantial number of bonus tracks.

On the first disc, these included "General Taylor" and three versions of the Buddy Holly song "Rave On!".

The quality of the recording was quite variable, but the bonus tracks include a number of pieces not released on any album.
