Links To PeelPeel welcomed the first Quicksilver Messenger Service LP, praising it in his column in International Times and playing the occasional track from it on Top Gear, but, as with its successor Happy Trails, he was unable to play the long tracks which were highlights of the LPs due to time constraints. Yet Quicksilver exercised an influence on a number of British bands who recorded sessions for his programmes in the early 1970s, including Cochise, and then Quiver and Help Yourself, who both played a Californian mixture of country rock and psychedelia and tried to live out the idea of being "community bands", playing for hippy audiences in London's Notting Hill (before its gentrification) and around the country, while avoiding "star trips". Man were also admirers of Quicksilver Messenger Service and John Cipollina guested with them on gigs during 1974-75.
In 1987, the subject of Quicksilver Messenger Service came up when Peel was discussing his earlier DJ career and Tony Blackburn with producer John Walters as part of the Peeling Back The Years series:
"Looking back on it ... he [Blackburn] by and large was right and I was wrong ... because he would say that Tamla Motown music was the stuff that would endure, and I would say, “No, no, it’s the music of the Quicksilver Messenger Service that is going to last forever.” And I think it is not unreasonable to say that he was right and I was wrong on that." 
Nevertheless, this did not prevent Peel from revisiting the first two Quicksilver LPs on his shows in subsequent years. In 2012, seven albums by the band were found when first details of Peel's record collection were released on TheSpace website.

There was one notable appearance a few years ago in Ipswich to which nobody came whatsoever, and even the promoters adjourned to the pub round the corner: and I was left standing in this deserted ballroom, with light streaming in through the windows, playing Quicksilver Messenger Service LPs to myself, and quite rightly too.")
